Raman spectra of tetragonal phase PbTeO3 have been acquired from single-crystal sample synthesized by hydrothermal method. Theory calculations have been carried out to analyze the Raman spectra. Raman bands between 600cm−1 and 800cm−1 are attributed to the internal modes of Te-O bonds in TeO3 pyrami...
