	abstract = {The optical Stark effect has been measured for the (B) over tilde (2)Sigma(+) - (X) over tilde (2)Sigma(+), 3(0)(1), and 2(0)(1)(P{\textquoteright}=3/2) bands of lanthanum imide, LaNH, prepared in a supersonic molecular beam. The permanent electric dipole moment, mu, for the (X) over tilde (2)Sigma(+) state was determined to be 2.53+/-0.06 D from measurements of the second-order Stark shifts in the (B) over tilde (2)Sigma(+)- (X) over tilde (2)Sigma(+), 3(0)(1) band. (nu(3) is the La-N stretching vibration, of symmetry sigma(+).) The dipole moment in the (B) over tilde (2)Sigma(+) state is too small to be determined from the Stark shifts in this band, but could be determined from the first-order Stark splittings in the P{\textquoteright}=3/2 component of the (B) over tilde (2)Sigma(+), 2(1) bending fundamental (of upper state pi symmetry); it was found to be 0.3+/-0.2 D. A comparison is made with LaO and other isovalent molecules involving Group IIIA atoms. (C) 2003 American Institute of Physics.},

	abstract = {The (0,0) band of the B (II)-I-4-X (4) Sigma(-) transition of NbO, near 6600 Angstrom, has been analyzed from spectra taken at sub-Doppler resolution. The transition is notable for the great width of its Nb nuclear hyperfine structure, which is caused principally by the unpaired 5s sigma electron in the ground state interacting with the large magnetic moment of the(41)(93) Nb nucleus (1=9/2). A fit to the ground-state combination differences, including four very precise microwave lines measured by Suenram et al. [J. Mol. Spectrosc. 148, 114 (1991)], has given a comprehensive set of rotational, spin, and hyperfine parameters. Prominent among these are the third-order spin-orbit distortions of the spin-rotation interaction and the Fermi contact interaction, which are large and well. determined, reflecting different degrees of spin-orbit contamination of the the (4) Sigma(1/2) and (4) Sigma(3/2) components of the ground state. The delta(2) pi B (II)-I-4 state was hard to fit, for a number of reasons. First, its spin-orbit structure is asymmetric, because of strong perturbations by a (II)-I-2 state which has been identified in this work, from among the various weak bands in the NbO spectrum near 7000 Angstrom; the result is that many high order centrifugal distortion terms are needed in an effective Hamiltonian model for the rotation. Second, the hyperfine structure is perturbed, not only by this (II)-I-2 state, but by distant Sigma and Delta states at higher energy. The delta(2) sigma* C (4) Sigma(-) State at 21 350 cm(-1) appears to be one of these. The distant states generate large apparent nuclear spin-rotation interactions, both within and between the Lambda components of the II state, as a result of cross terms between matrix elements of the operators -2BJ.L and aI.L. Similar cross terms arising from the operators AL.S and aI.L produce corrections to the Fermi contact matrix elements and are responsible for the unexpected negative sign of the magnetic hyperfine parameter d. The {\textquoteright}{\textquoteright}off-diagonal{\textquoteright}{\textquoteright} quadrupole parameter e(2)Qq(2) is very large, and causes some of the higher J line shapes of the B-X system to be noticeably asymmetric at Doppler limited resolution; its value is consistent with the electron configuration of the B (II)-I-4 state being delta(2) pi.},

	abstract = {High-resolution intracavity dye laser spectroscopy has been used to obtain sub-Doppler spectra of transitions to 350 rotational levels in the 4(0)(1) band of the ($) over tilde A (1)A(2)-($) over tilde X (1)A(1) electronic transition of thioformaldehyde. Ground state combination differences from the sub-Doppler spectra, combined with microwave and infrared data, have been used to improve the ground state rotational and centrifugal distortion constants of H2CS. The upper state shows a remarkable number of perturbations. The largest of these are caused by nearby triplet levels, with matrix elements of 0.05-0.15 cm(-1). A particularly clear singlet-triplet avoided crossing in K-a{\textquoteright} = 7 has been shown to be caused by interaction with the F-1 component of the 3(1)6(2) vibrational level of the ($) over tilde a (3)A(2) state. At least 53\% of the S-1 levels show evidence of very small perturbations by high rovibronic levels of the ground state. The number of such perturbations is small at low J, but increases rapidly beyond J=5 such that 40\%-80\% of the observed S-1 levels of any given J are perturbed by ground state levels. Model calculations show that the density and J dependence of the number of perturbed levels can be explained if there is extensive rotation-induced mixing of the vibrational levels in the ground state.},
