Sv. Trukhanov et al., EFFECT OF THE COMPONENTS OF THE RAMAN-SCATTERING TENSOR ON BAND INTENSITIES, Journal of structural chemistry, 37(6), 1996, pp. 855-862
The Raman scattering (RS) tensor as a function of excitation radiation
frequency is studied taking into account the vibration quantum. It is
shown that the corresponding asymmetric components of the tensor are
described by fast converging series. Expressions are obtained for the
antisymmetric and symmetric components of the RS tensor. A convenient
formula is proposed for the calculation of the RS tensor and its compo
nents, where the tensor is represented as a sum of the derivative of s
tatic polarizability and the terms containing fast converging series.
The formula makes it possible to avoid infinite summation. Computer ex
periments simulating the dependence of the intensity of RS bands and t
heir components on the excitation frequency are carried out.
