摘要
A short range force constant model has been applied to investigate the lattice dynamics of NaMnF3 in its orthorhombic phase. The calculated zone-centre Raman frequencies agree fairly well with the measured values. The infra red measurements have been assigned the proper species for the first time on the basis of the present calculations.
