INTENSITY IN THE RAMAN EFFECT: III. THE EFFECT OF DEUTERIUM SUBSTITUTION ON THE INTENSITY OF RAMAN BANDS OF BENZENE

Abstract

Standard intensities of the Raman bands of C6H6, 1,3,5,-C6H3D3, and C6D6 have been obtained photoelectrically. An ambiguity in the vibrational assignment for 1,3,5,-C6D3H3 has been removed, and the assumption of the invariance of the polarizability and anisotropy derivatives upon isotopic substitution has been tested. A sum rule for depolarization ratios of Raman bands in isotopic homologues has been derived subject to the same assumptions used for obtaining the intensity sum rules.
