| Abstract: | Measurements of some low frequency phonon dispersion curves in potassium thiocyanate have been made using inelastic neutron scattering techniques. The measured phonon frequencies are presented along with ones calculated from a simple model comprising axially-symmetric force constants between nearest neighbour atoms. The applicability of such a model in describing the lattice dynamics of this crystal structure is discussed. |
