dc.description.abstractEn | Raman spectra of the tetragonal D4/4 structure of paratellurite TeO2 have been revisited avoiding anomalous polarization-selection-rules violations previously observed and due to optical activity. We present a complementary hyper-Raman scattering study of paratellurite. Wavenumber and symmetry assignments are given for all expected 21 Raman active optical branches, except one LO component (out of the eight expected TO-LO pairs) of the polar doublet E modes. Also, the four expected hyper-Raman active A2 (TO) modes have been observed. Moreover, we have observed a strong Kleinman-disallowed hyper-Rayleigh signal, which is tentatively assigned as a first evidence of hyper-Rayleigh optical activity. | |
