Abstract
It is shown that an ionic model with polarization terms gives reasonable values for the vibrational frequencies of linear symmetric MX2 molecules. The potential function of such a model is indistinguishable from the valence force potential with interaction terms and this result is general for all molecules. Contrary to the literature, even a central force potential will give a nonzero bending frequency for a linear symmetric molecule.This publication has 8 references indexed in Scilit:
