We report a phonon density of states measurement of α-ZnCl2 using the coherent inelastic neutron scattering technique and a lattice dynamical calculation in four crystalline phases of ZnCl2 using a transferable interatomic potential. The model calculations agree reasonably well with the available experimental data on the structures, specific heat, Raman frequencies and their pressure variation in various crystalline phases. The calculated results have been able to provide a fair description of the vibrational as well as the thermodynamic properties of ZnCl2 in all its four phases.
