[en] The infrared intensities (and wavenumbers) for the fundamental vibrations of ClF₅, BrF₅, and IF₅ have been predicted, using an atomic polar tensor for the F atom transferred from the CH₃F molecule, together with matrices obtained from the normal coordinate analysis of each molecule. The procedure used in these predictions has been described previously in detail for the prediction of infrared intensities of SF₆ and UF₆. Comparison of the calculated intensities with the experimental spectra of XF₅ molecules reveals that the predicted values are in fairly good agreement with the experimental values. The model and procedure allow prediction of intensities of binary combination and overtone bands as well as fundamental vibrations. The comparison between prediction and experiment is presented in some detail, and some reasons for the (relatively few) apparent discrepancies are discussed
