Abstract

Angular dependencies of the Raman modes frequency on direciton of phonon wave vector q in tetragonal gyrotropic crystals TeO₂, ZnP₂, and CdP₂ were investigated and compared. We observed two completely different types of angular behavior of E-doublets splitting in depending on relative contributions of spatial dispersion and long-range Coulomb interaction. The explanation of apparent anomalous dependence of E-doublet 122 cm^-1 splitting on q in TeO₂ is proposed.
