	abstract = {A novel method is exploited in this report to directly determine the relative detection sensitivity of the (2+1) resonance-enhanced multiphoton ionization (REMPI) bands of CH3 and CHD2 radicals. The basic idea is based on the simple fact that in an infrared (IR) absorption process the number of molecules being pumped from the lower state must be the same as the number of molecules in the excited upper state. Hence, the measured intensities of the respective REMPI bands should directly reflect their relative detection sensitivities. In order to ensure the processes involved and better quantify the measurements, extensive IR-UV double resonance spectroscopy was also performed. Using the REMPI-IR scheme, the IR spectrum of the vi fundamental (CH stretch) of CHD2 was obtained and assigned for the first time. Using the IR-REMPI approach, high-resolution (2+1) REMPI spectra via the Rydberg 3p states of both radicals were demonstrated in a rotationally specific manner for both the origin and vibronic-excited bands, from which the predissociation rates of the Rydberg 3p states were deduced.},

All members of the six core-penetrating Rydberg series in the n* = 17-20 region and several components of the 17f and 17g core-nonpenetrating Rydberg states have been assigned. While the assignment of core-penetrating Rydberg states is straightforward without use of an effective Hamiltonian model, "spectrum-only" assignment of core-nonpenetrating states is complicated because strong l-uncoupling causes the core-nonpenetrating states to evolve rapidly from Hund{\textquoteright}s case (b) to Hund{\textquoteright}s case (d) coupling. We describe "spectrum-only" assignment procedures, developed in the spirit of Gerhard Herzberg, that can be used to assign optical-optical double-resonance spectra of core-penetrating and core-nonpenetrating Rydberg states using only information contained in the spectrum rather than predictions derived from an effective Hamiltonian model. The ambiguities that arise in the assignment of each class of states are discussed in detail.},

The spectra were observed with a cavity pulsed jet Fourier transform microwave spectrometer in the frequency range 5-24 GHz. The molecules were prepared by laser ablation of La metal and allowing the resulting plasma to react with SF6, Cl-2, Br-2, or CH3I precursor in an Ar carrier gas of the pulsed jet. For LaBr this is the first reported spectrum of any kind. Rotational constants, centrifugal distortion constants, nuclear quadrupole coupling constants, and nuclear spin-rotation constants have been determined for all the molecules. Accurate equilibrium (r(e)) internuclear distances have given an indication of where the Born-Oppenheimer approximation is beginning to fail. From the centrifugal distortion constants and vibration-rotation (alpha(e)) constants good estimates of the harmonic vibration frequencies and bond dissociation energies have been obtained. The halogen nuclear quadrupole coupling constants indicate the molecules to be highly ionic. (C) 2003 Elsevier Science (USA). All rights reserved.},

Data for the (0,0) band have been obtained for TiO molecules containing all the naturally occurring Ti isotopes but, for the weaker (1,0) band, only for (TiO)-Ti-48. Rotational constants for the two upper state vibrational levels were derived by fitting the data to an effective Hamiltonian; equilibrium parameters have been calculated. The experimental results are compared to the results of ab initio calculations on the E-X system. Ab initio results for the b-a system and for the lowest (3)Sigma(-) state are also presented.

Through least squares fits, parameters describing rotational, fine, and hyperfine effects (such as Fermi-contact, dipole-dipole coupling, and nuclear spin-rotation coupling) are presented. Trends in this halide series show an increasing amount of unpaired spin-density on the halide nucleus with increasing halide atomic number, which is consistent with results obtained in previous studies of the calcium analogs.

The radical was produced in an electric discharge using tetramethylsilane as the precursor. Fifteen cold bands of SiCH and 16 bands of SiCD have been assigned vibrationally, giving the upper state frequencies as v(2)({\textquoteright})=715/558 cm(-1) and v(3)({\textquoteright})=1168/1127 cm(-1) for SiCH/SiCD.

	abstract = {Laser excitation spectra of yttrium monohydroxide, YOH, have been recorded in the 500-625 nm wavelength region. Rotational analysis of bands of YOH and YOD has shown that the ground state is (X) over tilde(1)Sigma(+), with the structure r(0)(Y-O) = 1.948(6) Angstrom, r(0)(O-H) = 0.920(6) Angstrom; the bending frequency (nu(2), pi) is 313.73 cm(-1) (237.43 cm(-1) in YOD) and the Y-O stretching frequency (nu(3), sigma(+)) is 673.83 cm(-1) (655.34 cm(-1)). Two excited electronic states have been identified; they are assigned as (B) over tilde(1)Pi (16 449 cm(-1)) and (C) over bar(1)Sigma(+) (18 509 cm(-1)). Unusually strong vibronic coupling through the bending vibration occurs between these two states, which causes their vibrational structures to be highly irregular; assignments have only been possible following extensive wavelength-resolved fluorescence experiments. The vibronic coupling raises the bending frequency of the (C) over tilde(1)Sigma(+) state to 457 cm(-1) and reduces that of the lower Born-Oppenheimer component of the (B) over tilde(1)Pi state (which has A{\textquoteright} symmetry in the C, point group) to the extent that the molecule becomes nonlinear, with a potential barrier at the linear configuration of about 120 cm(-1). The presence of the potential barrier is clearly demonstrated by the level structure of YOD, where the Sigma(+) vibronic component of the 010 vibrational level (linear molecule notation) lies 1.4 cm(-1) below the 000 level. The upper Born-Oppenheimer component, which has A " symmetry, is unaffected; its bending frequency is similar to that of the ground state. Perturbations occur in both the (B) over tilde(1)Pi and (C) over tilde(1)Sigma(+) states; some of these represent local interactions between the two of them, but others are caused by higher vibrational levels of lower-lying "dark" electronic states. Over 40 ground state vibrational levels have been identified for both YOH and YOD from the wavelength-resolved fluorescence spectra. (C) 1999 Academic Press.},

	abstract = {Laser excitation spectra of gaseous CoO have been recorded using Doppler-limited intracavity spectroscopy and supersonic jet-cooled molecular beam methods, As seen in the molecular beam spectra there are nearly 100 bands arising from the X4 Delta(7/2) spin component of the ground state in the wavelength region 430-720 nm. All of them are very strongly red-degraded and most of them are perturbed, Co-59 hyperfine broadenings or splittings have been observed in many. The bands can be arranged into five electronic transitions, together with a considerable number of "extra" bands induced by perturbations; two of the excited electronic states are (4) Phi, while the other three, which lie within 1700 cm(-1) are (4) Delta. Semi-empirical calculations have been carried out for the (4) Delta excited states, using exchange integrals transferred from the TiO and VO spectra; the predicted energies, spin-orbit structures, and relative intensities in absorption are consistent with the assignment of all three (4) Delta states to the same electron configuration, (4s sigma)(1) (3d delta)(3)(3d pi)(2)(3d sigma)(1) It seems that there are extensive interactions between the excited (4) Delta states, because only one of them gives rise to a recognizable, though irregular, long vibrational progression in absorption. The other two progressions die out abruptly and unexpectedly after three or four members, presumably as a result of interference effects; however, wavelength-resolved fluorescence studies, together with calculations of the Franck-Condon overlap integrals to the various vibrational levels of the ground state, show that the upper state progressions reappear following a region of confused absorption. All of the excited states show highly irregular variations of their vibrational intervals and rotational constants with the vibrational quantum number, v. The wavelength-resolved fluorescence spectra give evidence for new low-lying electronic states of CoO at 3038, 5989, and 9105 cm(-1) based on its vibrational frequency the 3038 cm(-1) state is possibly the sigma delta(4) pi(2)B(4) Sigma(-) state.

The X(2) Sigma(+) ground state of CoC is an unusually good example of Hund{\textquoteright}s case (b(beta S)) coupling. Since Co has a nuclear spin I=7/2, each rotational level is split by the Fermi contact interaction into G=3 and G=4 components, where G=I+S; the splitting for N=0 is more than 0.5 cm(-1). The X(2) Sigma(+) state begins to uncouple toward case (b(beta J)) with increasing rotation. Transitions to various (II)-I-2 excited states occur in the region 13 000-14 500 cm(-1); the most prominent of these (for which high resolution spectra have been recorded) lie at 13 079 cm(-1) ((II3/2)-I-2) and 13 343 cm(-1) ((II1/2)-I-2). The (b(beta S)) coupling in the ground state produces some unexpected hyperfine intensity patterns, which have been studied in detail. A very low-lying (2) Delta(i) state, whose Omega=5/2 and Omega=3/2 components lie at 221 and 1173 cm(-1), has been identified. Laser excitation of the (II3/2)-I-2-(2) Delta(5/2) transition has been observed by monitoring the strong (II3/2)-I-2-X(2) Sigma(+) emission, which has allowed the (2) Delta(5/2) state to be characterized at high resolution. A total of 879 rotational-hyperfine transitions between the various (II1/2)-I-2, (II3/2)-I-2, (2) Delta(5/2), and (2) Sigma(+) states have been assigned and fitted.

	abstract = {Pure rotational spectra of six isotopomers of the rare gas trimer Ne-2-Kr and five isotopomers of the trimer Ne-2-Xe have been measured in their ground vibrational states using a Balle-Flygare-type cavity pulsed microwave Fourier transform spectrometer. Rotational constants have been evaluated, from which the geometries of the complexes have been derived. In the case of Ne-2-Kr it has been possible to obtain centrifugal distortion constants and to carry out a force field analysis. The magnitudes of the induced dipole moments of these trimers have been estimated from the {\textquoteright}{\textquoteright}pi/2 condition.{\textquoteright}{\textquoteright} The nuclear quadrupole hyperfine patterns due to Kr-83 and Xe-131 have been resolved, and the corresponding quadrupole coupling constants have been obtained. Observation of the spectra of these fundamental trimers has made it possible to compare their properties to those of their constituent rare gas dimers. The effects of three-body nonpairwise additive forces have been discussed in light of the structures obtained, the estimated induced dipole moments, and the nuclear quadrupole coupling constants.},

	abstract = {The microwave rotational spectra of the van der Waals trimers Ar2-OCS, (Ar2-OCS)-S-34, and (Ar2-OCS)-18 have been observed between 7.0 and 18.0 GHz using pulsed molecular beam microwave Fourier transform (MWFT) spectroscopy. Sixty-five transitions, both a and c type, have been assigned for Ar2-OCS, as well as 37 transitions and 19 transitions for (Ar2-OCS)-S-34 and (Ar2-COS)-O-18 respectively. The rotational constants and quartic centrifugal distortion constants have been determined. The trimer has been found to be a distorted tetrahedrally shaped highly asymmetric top (K= approximately 0.377) with the OCS subunit lying in the C(s) symmetry plane. An effective ground state structure has been determined. The Ar-Ar distance and the two {\textquoteright}{\textquoteright}Ar-center of mass of OCS{\textquoteright}{\textquoteright} distances are slightly longer than those in the corresponding dimers Ar2 and Ar-OCS, respectively. A harmonic force field analysis has been performed on the basis of the centrifugal distortion constants, to predict the van der Waals force constants and the corresponding vibrational frequencies. The Ar-Ar stretch force constant of the trimer is 0.008 42 mdyn angstrom-1 which compares favorably with 0.0078 mdyn angstrom-1 reported for the free dimer Ar2. A comparison of the geometry and spectroscopic properties of Ar2-OCS with those of Ar2 and of the Ar2-HX (X = F, Cl, CN) trimers is given.},

	abstract = {The synthesis of the bis(carbonyl)gold(I) salt, [Au(CO)2] [Sb2F11], is achieved in a two-step procedure: the reduction of gold(III) fluorosulfate, Au(SO3F)3, in HSO3F to give AU(CO)SO3F as an intermediate, followed by solvolysis in liquid antimony(V) fluoride in the presence of carbon monoxide. The use of (CO)-C-13 or (CO)-O-18 permits the synthesis of the corresponding isotopically labeled salts. The compound is thermally stable up to 130-degrees-C. The cation has D(infinity h) symmetry, and all seven fundamentals, three Raman and four IR active modes, are observed. A normal coordinate analysis (NCA) and general valence force-field (GVFF) calculations are carried out and allow comparison to the isoelectronic and isosteric molecular species Hg(CN)2 and [Au(CN)2]-. The near absence of gold to carbon pi-back donation in [Au(CO)2]+ is manifested in strong carbon-oxygen bonds and consequently rather weak gold-carbon bonds, reflected in the highest CO-stretching frequencies so far observed for a metal carbonyl derivative with 2254 (nu1) and 2217 (nu3) cm-1 and a stretching force constant of 20.1 X 10(2) Nm-1. In the C-13 NMR spectrum a single-line resonance at 174 ppm is attributed to ([Au(CO)2]+)-C-13, while the ([Au(CO)]+)-C-13 chemical shift changes from 162 ppm in HSO3F to 158 ppm in magic acid (HSO3F/SbF5). The resonances for ([Au(CO)2]+)-C-13 and ([Au(CO)]+)-C-13 in the same solution are found to undergo coalescence at elevated temperature indicative of slow CO exchange. The coalescence temperature is solvent dependent, 325 K in HSO3F and 395 K in the more dilute HSO3F/SbF5 mixture. Attempts to recrystallize [Au(CO)2] [Sb2F11] from acetonitrile result in the formation of single crystals of [Au(NCCH3)2][SbF6] instead. The compound crystallizes in a cubic unit cell, space group Pa3BAR, with a = 10.250 (2) angstrom and Z = 4. The structure was determined by Patterson and Fourier methods and refined by least-squares techniques to R = 0.023 and R(w) = 0.024 for 147 reflections with I > 3sigma(I). The crystal contains linear [Au(NCCH3)2]+ cations and octahedral [SbF6]- anions, with normal dimensions.},
