Popis:	The temperature dependence of the one phonon Raman spectra of ZnS (hex.), ZnO and a-Sic crystals is studied over the temperature range 15 to 1000 K. For ZnS frequency shifts are calculated by Griineisen theory and the k = 0 longitudinal and transverse optic phonon Griineisen parameters determined. The results are compa, indicating that the principal interactions are the cubic anharmonicities. Various calculated properties include the area, second moment, and simulated Raman bands to illustrate the anharmonic behaviour in the solids.
