| Popis: | The features of the physicochemical mechanisms that cause absorption bands related to cluster translational vibrational dynamics to be formed in the low-frequency IR spectra of molecular liquids are analyzed in terms of the concepts of the cluster-continuum approximation of the method of thermodynamic functionals of generalized internal coordinates. Based on the harmonic oscillator model, a new relationship is obtained that relates the effective structure parameter of the translational intermolecular vibrations in liquids to the corresponding vibrational frequencies. © 2005 Optical Society of America |
