Abstract

Polarized Raman scattering spectra of LiGa₅O₈ are observed at room temperature. Two adjacent peaks are newly found in a low frequency region (128 and 135 cm⁻¹). By the site symmetry consideration, we concluded that these peaks correspond to the doubly degenerate and the non-degenerate modes of the translational motion of GaO₄ at the tetrahedral site. These two modes are the ones derived by splitting of the triply degenerate translational mode in the disordered state when the order-disorder transition occurs at 1140°C.
