| 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 components, where the tensor is represented as a sum of the derivative of static polarizability and
the terms containing fast converging series. The formula makes it possible to avoid infinite summation. Computer experiments
simulating the dependence of the intensity of RS bands and their components on the excitation frequency are carried out.
