N2 - Bond polarizability calculations extended for hyper-Raman scattering by the optical LO and TO zone-centre phonons in sodium, potassium and rubidium halides are presented. The effect of the crystal ionicity on both of the independent hyper-Raman tensor components is taken into consideration. Contributions of rotation of crystals bonds and their stretching to hyper-Raman scattering are determined. For LO phonons the electrooptic part of the hyper-Raman tensor is found. The results obtained are compared, when possible, with experimental and theoretical data reported in the literature.
