Laser‐induced Raman spectra were obtained for powders and multidomain single crystals of PbZrO 3 at room temperature. Factor‐group analysis was used to interpret the spectra on the basis of the space group C 2v 8 ‐Pba 2. Raman spectra were also observed for single crystals of PbZrO 3 at several other temperatures between 76° and 520°K and related to crystal structural changes. No first‐order Raman bands were noted above the Curie temperature, indicating a phase transformation to a cubic zirconate structure. The interpretation of Raman spectra for thermally decomposed PbZrO 3 is discussed.
