Abstract
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.
