Before analyzing the optical spectra of some M/sup 4 +/ ions diluted in ThSiO/sub 4/, Raman and infrared studies were undertaken on a single crystal of thorite. Indeed a strong coupling between the electronic transitions within the f band and the vibrations of the host lattice is expected. All the active modes of vibration at k = 0 of ThSiO/sub 4/ were assigned in the D/sub 4h/ point group. Raman scattering spectra recorded between 300 and 4.2 K have shown that the crystalline structure of thorite does not change down to 4.2 K.
