Abstract

Polarization and temperature dependence of Raman scattering spectra of CuGeO3 has been measured from room temperature to 5 K. The observed phonons at room temperature are well assigned by the group theoretical estimation for Pbmm(D52h). The qualitative change for all possible Raman scattering spectra has not been found from room temperature to 14 K. The energy of the five inter-chain phonons increases with decreasing temperature. Below spin-Peierls transition temperature Tsp (=14 K), five peaks at 27, 107, 230, 370, and 820 cm-1 have been observed for the (c, c) geometry while the peaks at 370 and 820 cm-1 appear for (b, c).
