Abstract

The dipole and rotational strenghts of the C-H and C-D stretching modes of trans-2,3-dideuteriooxirane are calculated and used to predict vibrational absorption and circular dichroism spectra. The requisite atomic polar and axial tensors are obtained by using the random phase approximation (RPA), a «polarized» basis set, and the distributed origin gauge. The results are in excellent agreement with experiment
