Electro-optical parameters and Raman intensities of CH4, CH3D, CH2D2, CHD3 and CD4

The absolute Raman intensities and the depolarization ratios of the vibrational bands of gaseous CH4, CH3D, CH2D2, CHDS and CD4 have been computed here using a compact formulation of the bond polarizability theory, in its zero and first-order approximations. The agreement with experimental values ta...

Sumario:The absolute Raman intensities and the depolarization ratios of the vibrational bands of gaseous CH4, CH3D, CH2D2, CHDS and CD4 have been computed here using a compact formulation of the bond polarizability theory, in its zero and first-order approximations. The agreement with experimental values taken from the literature is very good for the first-order approximation, although the difference between both approximations is not very large for these molecules. The derivatives of the polarizability with respect to the symmetry coordinates of methane are given with signs that are physically meaningful. © 1976 Taylor & Francis Group, LLC.
