✦ Synopsis


The cubic and quartic force fields of (\mathrm{AsH}{3}, \mathrm{SbH}{3}), and (\mathrm{BiH}{3}) are determined from ab initio calculations using effective core potentials and polarized double-zeta valence basis sets. The computed geometries, dipole moments, rotational constants, vibration-rotation interaction constants, (l)-doubling constants, anharmonicity constants, vibrational wavenumbers, centrifugal distortion constants, and Coriolis coupling constants are compared with the available experimental data for (\mathrm{AsH}{3}) and (\mathrm{SbH}{3}). The vibrational wavenumbers and other spectroscopic constants for the (\mathrm{BiH}{3}) molecule are predicted. (c) 1995 Academic Press. Inc.

The molecular geometry and the harmonic and the anharmonic components of the force field of FSN have been evaluated by the SCF and, to account for electron correlation, by the MP2 and CASSCF methods. Comparison with experiment of the theoretical geometry, dipole and force constants shows that SCF an

## Abstract The geometry, harmonic and anharmonic force fields, and fundamental vibrational frequencies of __cis__‐ and __trans__‐thiolformic acid are studied __ab initio__ in the 4‐31G basis set. An extensive comparison is made between changes in diagonal and off‐diagonal quadratic and cubic force
