Abstract
A microscopic approach which permits Raman scattering in a dielectric crystal is presented to be described in a uniform way. Additional features of the temperature dependences in the spectrum of Raman scattering of phonons are obtained, arising owing to presence of low-lying nearly degenerated electronic levels typically occurring in crystals with Jahn–Teller phase transitions. The changes in the populations of these levels may influence the temperature dependences in Raman spectra. The theory describes also the electronic Raman effect in these crystals.
