✦ Synopsis

The Hamiltonian of the induction effect (dipole-induced dipole interaction) in the model proposed by Snels and Reuss is corrected. This model was proposed for the calculation of the frequency shift and transition strength of the IR spectra of clusters of highly symmetric molecules such as (SF,),, (SiF,), and (SiH,),. Disagreement between the observed frequency shifts and the calculated results obtained using this model for (SF,), and (SF,), was found to be caused by the incorrect Hamiltonian of the dipole-induced dipole interaction. The calculated results for (SF,), and (SF,), with the corrected Hamiltonian agree with the observed spectra.
