Abstract
The FT-IR spectra of mixtures of HCl and the following compounds have been recorded in the gaseous and matrix isolated phases: argon, ethene, ethyne, d
6-benzene, fluorobenzene, CO, CO
2, SO
2, CCl
4, CHCl
3, d
6-acetone, ethanal, HCN, acrylonitrile. The features which are measured are: firstly the changes in the integrated intensity of lines in the rotation—vibration spectrum of the fundamental HCl band as a function of non-specific interactions with other components of the mixture and secondly bands associated with specific interactions forming hydrogen bonded complexes in the gas and matrix isolated phases. The relationship between the two kinds of interactions is discussed.
