摘要: Abstract The room-temperature infrared and Raman scattering spectra of a large group compounds with the general formula M2Cu2O5 were examined in polycrystalline state (M is either Sc, In Y or heavy rare-earth element from Tb to Lu). identification bands observed for respective vibrational modes was proposed on basis factor approach normal coordinate analysis. Urey-Bradley force field model potential energy distribution applied phonon calculations.
