Zone center wavenumbers of the orthorhombic LaGaO3 perovskite

A short-range force constant model was applied for the first time to investigate the phonons in LaGaO3 perovskite in the orthorhombic phase. The calculations with 10 stretching and 10 bending force constants provide good agreement for the observed Raman and infrared wavenumbers. The infrared wavenumbers at 329, 308, 296 and 165 cm−1 were assigned to the B1u mode and those at 510, 416, 353 and 275 cm−1 to the B3u mode. Copyright © 2000 John Wiley & Sons, Ltd.
