| Abstract: | A short range force constant model has been applied to investigate the phonons in YAlO3 perovskite in the orthorhombic phase. The calculations with six stretching and one bending force constants provide a satisfactory agreement for the available Raman frequencies. Based on the present calculations, the infrared frequencies have been assigned for the first time. |
