A general theory of Raman scattering (RS) by polaritons in anisotropic crystals with an arbitrary number of phonon branches is developed. A classification of possible scattering variants is given for both uniaxial and cubic crystals. Formulas defining the angular dependence of the integral intensity and scattering line shape are obtained. Some possible ways of determining the ratios of electronic—ionic and pure electronic contribution to the RS intensity are discussed. The scattering intensity by longitudinal phonon is also investigated.
