The Hamiltonian of the induction effect in infrared spectra of SF6 clusters

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 (SF6)n (SiF4)n and SiH4)n Disagreement between the observed frequency shifts and the calculated results obtained using this model for SF6)3 and SF6)4 was found to be caused by the incorrect Hamiltonian of the dipole-induced dipole interaction. The calculated results for SF6)3 and SF6)4 with the corrected Hamiltonian agree with the observed spectra.
