	abstract = {The electronic spectrum of NiCN in the 500-630 nm region has been observed by laser-induced fluorescence, following the reaction of laser-ablated nickel atoms with cyanogen under free jet expansion conditions. Seven electronic states hake been identified. Three of these, (X) over tilde (1) (2)Delta(5/2), (X) over tilde (2) (2)Delta(3/2), and (W) over tilde (2)(1)Pi(3/2), are derived from the electron configuration Ni+ (3d(8) 4s) CN, and the other four, (A) over tilde (2) Delta(5/2), (B) over tilde (2)Pi(3/2), (C) over tilde (2)Phi(7/2) and (D) over tilde (2)Phi(5/2), are derived from the configuration Ni+ (3d(8) 4s) CN. Rotational analysis of bands of (NiCN)-N-14 and (NiCN)-N-15 at high resolution has given the bond lengths in the (X) over tilde (2)(1)Delta(5/2) ground state as r(0) (Ni-C) = 1.8292 +/- 0.0028 Angstrom; r(0) (C-N) = 1.1591 +/- 0.0029 Angstrom. The orbital angular momentum splits the bending fundamental of the (X) over tilde (2)(1)Delta(5/2) state into two vibronic components, which lie at 243.640 cm(-1) ((2)Pi(3/2)) and 244.964 cm(-1) ((2)Phi(7/2)). Exceptionally strong Fermi resonance occurs in the ground state between the Ni-C stretching vibration, nu(3), and the overtone of the bending vibration. Sixty vibrational levels of the ground state with /l/ = 0 and l have been assigned, They could tie fitted by least squares to a simple matrix representation of the Fermi resonance that ignores the orbital angular momentum the interaction matrix element, as a fraction of the bending frequency, turns out to be larger than that in the "prototype" molecule, CO2. The two low-lying excited electronic states, (X) over tilde (2)Delta(3/2) at 830 cm(-1) and (W) over tilde (2)(1)Pi(3/2) at 2238 cm(-1), have very similar properties to the ground state. The energies of the excited states in the visible region bear a remarkable resemblance to those found in NiH (S, A. Kadavathu et al., 1991, J. Mol. Spectrosc. 147, 448-470). Again, the effects of Fermi resonance in them are large but those of vibronic coupling are surprisingly small. The most significant vibronic coupling occurs between the (A) over tilde (2)Delta(5/2) and (B) over tilde (2)Pi(3/2) states, which are separated by 79 cm(-1), an interval which is less than half the frequency of the bending vibration that couples them large numbers of vibronically induced bands appear in the excitation and dispersed emission spectra, but the splitting between (tie vibronic components of the bending fundamental of the (A) over tilde (2)Delta(5/2) state is only 6.988 cm(-1). Rotational perturbations are widespread in the (A) over tilde (2)Delta(5/2) state, particularly in the levels of the nu(3) (Ni-C stretching) progression, Vibrational assignments have been made on the basis of the Ni-58-Ni-60 isotope shifts at high resolution and the Franck-Condon patterns in dispersed emission spectra, Various weak unassigned bands, both in the excitation and the dispersed emission spectra, give evidence for the existence of at least three more excited electronic states which it has not been possible to characterize in detail.

Three types of experiment have been carried out. First, the complete rotational and hyperfine structures of the two bands were recorded. To Measure the small asymmetry splittings in the K = 2 levels of the X(2)A(1), state, portions of the b-type 3(0)(1) and were then recorded in the presence of a weak static electric field. Finally, a number of pure rotational transitions between the K = 0 levels of the ground state were recorded by pump/probe microwave optical double resonance. A few small rotational perturbations occur in the upper electronic state but omitting the perturbed lines, the combined data sets could be modeled using an effective Hamiltonian operator appropriate for the rotation, electron spin, and hyperfine structure of a rigid asymmetric top molecule, The molecule is confirmed as being "T-shaped." where the Y atom is bonded to the side of a C-2 group: the rotational Constants determined are for the A(2)A(1), 3(1) level},

	abstract = {The infrared Fourier transform spectrum of (CH3OH)-O-18 has been recorded in the region from 1020 to 1620 cm(-1) at high resolution in order to study the low-lying bending modes, including the CH3-rocking, OH-bending, and CH3-deformation fundamental bands. More than 10 000 lines have now been assigned in this region. The present paper focuses on the n = 0 ground torsional subbands of the in-plane CH3-rocking fundamental. This band is principally of parallel a-type character, due to mixing of the predominantly parallel CO-stretching and OH-bending coordinates with the perpendicular rocking coordinate. Some b-type character was also observed, with partial assignments of a number of weak perpendicular subbands. The parallel subbands have been fitted to J(J + 1) power-series expansions to obtain the subband origins, as well as compact representations of the data in terms of phenomenological state-specific expansion coefficients. The n = 0 excited state energies calculated from the subband origins follow a similar oscillatory pattern with K to that of the ground vibrational state but with significantly reduced amplitude. Analysis with our basic torsion-rotation Hamiltonian yields an effective torsional barrier height for the rocking state of 474.5 +/- 2.8 cm(-1), a 27\% increase over the ground state value. The vibrational energy is found to be 1058.46 +/- 0.62 cm(-1). An interesting J-localized level-crossing resonance between the CH3-rocking and CO-stretching modes has also been observed through perturbations in the spectrum. (C) 1995 Academic Press, Inc.},

	abstract = {High-resolution pure rotational spectra of nitrosyl fluoride, FNO, and nitryl fluoride, FNO2, have been measured using a cavity pulsed microwave Fourier-transform spectrometer. The samples were prepared using a pulsed electric discharge through precursor substances, with the discharge apparatus mounted as part of the pulsed nozzle of the spectrometer. Nuclear quadrupole and magnetic hyperfine structures due to N-14 and F-19 have been resolved for both molecules, and precise values for the nuclear quadrupole and spin-rotation coupling constants have been obtained. The N-14 quadrupole coupling constants of FNO2 have been rationalized in terms of a sigma-withdrawal of electron density from NO2 towards F. This view is corroborated by the magnetic shielding estimated from the F spin-rotation constants.},

	abstract = {The pure rotational spectrum of the van der Waals complex Ar-Cl2 has been observed between 5 and 14 GHz using a Balle-Flygare type pulsed molecular beam microwave Fourier transform spectrometer. Ten a-type rotational transitions of Ar-Cl-35(2), as well as five a-type rotational transitions of the mixed isotopomer Ar-(ClCl)-Cl-35-Cl-37, have been assigned. The rotational constants and quartic centrifugal distortion constants have been determined. Unlike its isovalent linear isomer Ar-CIF, Ar-Cl2 has been found to be a T-shaped complex. This confirms the result from electronic spectroscopy and is in accord with the atom-atom additive model. The distance from the Ar nucleus to the center of mass of the Cl2 subunit has been calculated to be 3.7190 angstrom for Ar-Cl-35(2) and 3.7184 angstrom for Ar-(ClCl)-Cl-35-Cl-37, respectively. The van der Waals stretch and bend force constants, as well as their corresponding harmonic vibrational frequencies, have been derived and compared with the theoretically predicted values. The nuclear hyperfine splittings due to the two chlorine nuclei have been resolved and the coupling constants have been accurately determined. For Cl-35 these are (in MHz): chi(aa) = 54.8180(16), chi(bb) = -110.7131(19), chi(cc) = 55.8951(19) in Ar-Cl-35(2); and chi(aa) = 54.8407(27), chi(bb) = -110.706(20), chi(cc) = 55.866(20) in Ar-(ClCl)-Cl-35-Cl-37. For Cl-37 the values are chi(aa) = 43.2111(29), chi(bb) = -87.267(12), chi(cc) = 44.056(12) in Ar-(ClCl)-Cl-35-Cl-37. A value has been obtained for the nuclear quadrupole coupling constant in free diatomic chlorine.},
