Paper Abstract

The results of a study of vibrational spectra of volatile hydrides of the VA group elements of periods 2 - 4 in the liquid state and in solutions of liquefied noble gases have been generalized and analyzed over wide frequency and temperature ranges. A number of anomalies have been revealed in the spectra of these hydrides that manifest themselves through an unusual behavior of band intensities of basic, composite vibrations and overtones on a transition from the gas phase to the condensed state, and dependences of spectroscopic and dynamic parameters as well as a non- coincidence of the line maxima in isotropic and anisotropic Raman spectra ((delta) v equals vaniso-viso) on the temperature of liquid hydrides. Mechanisms of intermolecular interactions in these liquids are discussed with the use of the as-obtained data on the intensity, frequency and shape of vibrational band contours.
