We present for the first time a hyper-Raman scattering study of paratellurite. We have also revisited the Raman spectra of paratellurite. Anomalous polarization-selection-rules violations previously observed in Raman and due to optical activity are possible to avoid when light propagates at 45° of the Ox and Oy optical axes. From this single crystal study, all expected optical phonon modes frequencies and symmetries are given, except one E (LO) mode that could not be observed. We have evidenced a strong harmonic light scattering signal in the ZYY′ spectrum that we tentatively assigned to hyper-Raleigh optical activity that comes from a mixed dipolar electric–magnetic effect.
