## Abstract A short‐range force constant model has been applied to investigate the Raman and the infrared wavenumbers in R~2~BaNiO~5~ (R = Y, Gd) in their orthorhombic phase of space group __Immm__. Calculations of zone‐center phonons are made with seven stretching and four bending force constants.
