Electro-optical parameters and Raman intensities of CHCl₃and CDCl₃

Abstract

The absolute Raman intensities and depolarization ratios of CHCl3 and CDCl3 have been measured in the gas phase. These magnitudes, the Raman tensors (including signs), as well as the electro-optical parameters of the C-H and C-Cl bonds have been calculated within the frame of the bond-polarizability theory. Several approximations of the theory are reviewed. The influence of the vibrational force field upon the electro-optical parameters is also checked.
