Lattice dynamical calculations are reported for two possible space groups (Pnma and Cmc21). The force constants were found by varying the paramete 1's in appropriate semi-empirical inter-atomic potentia1 functions to obtain agreement with observed infra-red absorption frequencies. A frequency distr
