Systematic trends in the vibrational frequency shifts of some molecules trapped in amorphous water ice

摘要

This paper focuses on systematic examination of the vibrational frequency shifts of some molecules trapped in water ices. It is shown that for the bands, for which the laboratory taken data are available, the magnitude and the sign of a vibrational shift for the molecules trapped in water ice can be approximately predicted using empirical correlations with macroscopic properties of the host. These results can be useful for identification of the carriers of absorption in matrix spectroscopy, for the study of intermolecular interactions, for a number of applications involving remote spectroscopic sensing of molecular species in the atmosphere and in space.
