In the present article, the effective nuclear charge model is used to compute the valence force constants for tetrahedral molecules. The experimental force constants determined by normal co-ordinate analysis are compared with the computed results. The agreement between the results, are found to be reasonably good and hence, it is concluded that the said model is successful to predict the approximated valence force constants in complicated polyatomic molecules.

Keywords: Tetrahedral, valance force, nuclear charge.
