A short-range force constant model was applied to investigate the phonons in CaGeO 3 perovskite in the orthorhombic phase. The calculations with six stretching and bending force constants provide good agreement for the Raman wavenumbers. The correct assignments of the observed Raman wavenumbers were

A short-range force constant model was used to investigate the phonons in perovskite in the orthorhombic BaCeO 3 phase. The calculations with just 14 stretching and bending force constants provide good agreement for the Raman wavenumbers. The oxygen-oxygen interatomic forces are included explicitly
