	abstract = {The fine and hyperfine interaction parameters in the [18.8] (3)Phi (upsilon=0) and X (3)Phi (upsilon=0) states of cobalt monofluoride, CoF, have been determined from an analysis of high-resolution laser induced fluorescence spectra of the [18.8] (3)Phi(3)-X (3)Phi(3) and [18.8] (3)Phi(4)-X (3)Phi(4) band systems. The previously reported pure rotational transitions of the X (3)Phi(4)(upsilon=0) state [T. Okabayashi and M. Tanimoto, J. Mol. Spectrosc. 221, 149 (2003)] were included in the data set. The hyperfine parameters for Co-59 (I=7/2) and F-19 (I=1/2) have been interpreted using atomic data together with a proposed molecular orbital description for the [18.8](3)Phi(i) and X (3)Phi(i) states. A comparison of the hyperfine parameters in the X (3)Phi state of cobalt monohydride, CoH, with those of the X (3)Phi state of CoF reveals that the bonding in the two molecules is significantly different. It is shown that, in a situation where the Omega substates of a multiplet degenerate electronic state are analyzed separately, the Fermi contact parameter b can be determined with fair accuracy from the apparent centrifugal distortion of the hyperfine structure.

	abstract = {Pure rotational spectra have been measured for all the major isotopomers of the lanthanum monohalides, LaF, LaCl, LaBr, and LaI, in their ground and (except for (LaBr)-Br-81) excited vibrational states. 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.},

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 pure rotational spectrum of the free radical MgBr has been measured in its (2) Sigma(+) ground electronic state by Fourier transform microwave spectroscopy. Transitions have been observed for both (MgBr)-Mg-24-Br-79 and (MgBr)-Mg-24-Br-81 in the v = 0 and v = 1 vibrational states. Rotational and centrifugal distortion constants have been determined for each isotopomer in each vibrational state. Equilibrium rotational constants have been calculated and an accurate equilibrium bond length has been determined. Spin-rotation constants, for both the unpaired electron and the bromine nuclei, have been calculated along with magnetic and nuclear quadrupole hyperfine constants for the bromine nuclei. From these constants, the electronic structure of MgBr has been investigated and comparisons have been made to similar compounds. The unpaired electron spin density on the bromine nucleus has been found to be very small, suggesting that this is a very ionic compound. However, the Mg-Br bond has been found to have more covalent character than the bond in other alkaline earth monobromides. (C) 1997 American Institute of Physics. [S0021-9606(97)02046-1].},

	abstract = {The laser excitation spectrum of tungsten methylidyne, WCH, has been recorded in the 12 000-15 400 cm(-1) region. A total of 14 vibronic bands of WCH and 16 bands of WCD have been observed in this region. Rotational analysis shows that the ground state is (X) over tilde 3/2((2) Delta), with the substitution structure r(0)(W=C)=1.7366(5) Angstrom and r(0)(C-H)=1.076(5) Angstrom. The excited vibronic levels have been assigned, on the basis of their WCH/WCD isotope shifts and their wavelength resolved fluorescence patterns, to three electronic states, (A) over tilde 3/2((2) Delta), (B) over tilde 1/2((2) Pi), and (C) over tilde 5/2(2 Phi), at 12 090, 13 392, and 14 110 cm(-1), respectively. The wavelength resolved fluorescence spectra have also established the low-lying vibrational levels of the ground state. The ground state bending fundamental lies at 660 cm(-1), while the W-C stretching frequency is 1006 cm(-1); the corresponding frequencies in WCD are 501 cm(-1) and 953 cm(-1), respectively. No evidence for the C-H stretching frequency has been found. Emission has also been observed to a low-lying electronic state, 813 cm(-1) above the (X) over tilde 3/2 state. The pattern of rotationally resolved emission to this state clearly indicates that it is a (4) Sigma(1/2) state. Its bending frequency is 612 cm(-1), and its W-C stretching frequency is 971 cm(-1), indicating a slightly longer bond length than in the (X) over tilde 3/2 state. High resolution cw laser spectra of the (0,0) bands of the two lowest excited electronic states [(A) over tilde 3/2((2) Delta) and (B) over tilde 1/2((2) Pi)] reveal a small splitting of the four principal tungsten isotopes (W-182, W-183, W-184, and W-186) which serves to confirm the presence of tungsten in the carrier. Hyperfine splitting associated with the W-183 nucleus (I = 1/2) has been observed for the (0,0) band of the (A) over tilde 3/2- (X) over tilde 3/2 system, allowing the electron configuration of the ground state to be elucidated.
