The molecular parameters, i.e. force constants, mean amplitudes of vibrations, bond polarizability derivatives and mean molecular polarizabilities have been studied for MX2 and MXZ (M = Zn, Cd, Hg; X or Z = F, Cl, Br, I but X ##f Z) type halides of zinc group elements on the basis of current available spectroscopic and structural data. The analysis of the result for CdFBr demands a reinvestigation of the spectroscopic study in detail. The results of the present investigations will be helpful in the interpretation of the Raman intensity and refractometry data whenever available.
