	abstract = {The (0,0) and (0, 1) bands of the C(4)Sigma(-)-X(4)Sigma(-) electronic transition of VS (near 809 and 846 nm, respectively) have been recorded at high resolution by laser-induced fluorescence, following the reaction of laser-ablated vanadium atoms with CS2 under supersonic free-jet conditions. A least squares fit to the resolved hyperfine components of the rotational lines gives the rotational constants and bond lengths as C(4)Sigma(-): B-o = 0.188898 +/- 0.000027 cm(-1), r(o) = 2.1315 Angstrom; X(4)Sigma(-): B-0 = 0.203684 +/- 0.000025 cm(-1), r(o) = 2.0526 Angstrom. The electron spin parameters for the two states show that there are some similarities between the states of VS and those of VO, but the hyperfine parameters show that the compositions of the partly filled molecular orbitals are by no means the same. The ground state Fermi contact parameter of VS, b (X(4)Sigma(-)), is only 58\% of that of the ground state of VO, which implies that the sigma orbital of the ground sigmadelta(2) electron configuration has less than 50\% vanadium 4s character. Similarly, the excited state Fermi contact parameter, b(C(4)Sigma(-)), is very much smaller than that of VO. No local rotational perturbations have been found in the C(4)Sigma(-) state of VS, though an internal hyperfine perturbation between the F-2 and F-3 electron components at low N confuses the hyperfine structure and induces some forbidden (DeltaJ = +/-2) rotational branches.

	abstract = {High-resolution emission spectra of VO have been recorded in the region 3400-19400 cm(-1) using a Fourier transform spectrometer. The molecules were observed from the reaction of VOCl3 with active nitrogen. Two new bands, with origins near 5539.46 and 5551.69 cm(-1), are assigned as the 0-0 bands of the (2)Phi(5/2)-(2)Delta(3/2) and (2)Phi(7/2)-(2)Delta(5/2) spin-orbit components (respectively) of a (2)Phi-1(2)Delta electronic transition of VO. A rotational analysis of both subbands has been carried out and spectroscopic constants have been extracted. The 1(2)Delta state is known from the previous analysis of the near infrared doublet transitions of VO and the new (2)Phi excited state has rotational constants very similar to those of another (2)Phi state observed previously [Merer et al., J. Mol. Spectrosc. 125, 465 (1987)]. (C) 2002 Elsevier Science (USA).},

	abstract = {Electronic bands assigned to the linear TiCH and TiCD radicals have been recorded by laser-induced fluorescence in the 610-725 nm wavelength region, following the reaction of laser-ablated Ti atoms with methane under supersonic jet-cooled molecular beam conditions. Rotational analyses of high-resolution spectra have given the ground state substitution structure X(2) Sigma(+): r(g)(C-H) = 1.085 +/- 0.002 Angstrom: r(g)(Ti-C) = 1.7277 +/- 0.0003 Angstrom. The electronic upper state appears to be a very strongly perturbed (2) Pi start, with many extra rotational and vibrational levels appearing; it has nor barn possible to make vibrational assignments, though the Omega{\textquoteright} values have been established for some of the levels. Wavelength-resolved fluorescence spectra have given two of the three ground state vibrational frequencies: TiCH: nu(2)(bend) = 578 cm(-1), nu(3)(Ti-C stretch) = 855 cm(-1) TiCD: nu(2) = 442 cm(-1), nu(3) = 815 cm(-1) Vibrationally forbidden transitions to the ground state bending fundamental appear prominently in many of these spectra, as a result of strong vibronic coupling. No evidence for nu(1)(pi) (the C-Il stretching vibration) has been found. (C) 1997 Academic Press, Inc.},
