COMBINED METHOD FOR CALCULATING RAMAN BAND INTENSITIES WITH CONSIDERATION FOR THE DEPENDENCE OF THE RAMAN TENSOR ON THE FREQUENCY OF EXCITING RADIATION

It is shown that at certain assumptions the tensor of Raman bands can be represented as a sum of the Placzek term and the fast convergent se ries that contains information on the sensitivity of the tensor elemen ts to the frequency of exciting radiation. The convergences of the cor responding series and the frequency dependences of the Raman band inte nsifies for particular molecules are studied by computer experiments.
