A rigorous theory of vibrational rotational strengths was recently developed by Stephens. We report the first comparisons of calculations using this theory with experimental vibrational circular dichroism data. The theory is implemented using SCF MO electronic wavefunctions and a 4-31G basis set. Th

β¦ Synopsis
Calculations of the vibrational circular dichroism (VCD) and absorption spectra of propylene oxide over the range 700-1600 cm-' are compared with experimental spectra. VCD spectra are calculated using Stephens' equation for vibrational rotational strengths in the distributed origin gauge. Atomic polar and axial tensors are calculated at the SCF level of approximation. Scaled SCF force fields and calculated and corrected SCF equilibrium geometries are utilized.

The magnetic vibrational circular dichroism spectra of C6o fullerene in solution are presented for excitation of the 1430 and 1183 cm-l ttu-symmetry fundamental vibrations. These transitions give rise to A-term MVCD of opposite sign (A~/Do= -3.8 and l. 1 Γ 10-4, respectively) which are similar in ma
A theory of type B magnetic vibrational circular dichroism (MVCD) is developed and applied. The motion of the nuclei is treated classically and the momentum correlation between their motion and the electronic motion is treated explicitly.

Vibrational circular dichroism (VCD) spectra are reported for (+), (-) and (-+) a-pinene, and (-) /3-pinene, isolated in argon matrices at ~18 K. These are the first observations of VCD of matrix-isolated molecules. Spectra are limited to the C-H stretching region (2800-3100 cm -1 ). In all cases, t
