Abstract
The absolute intensities of fundamental and overtone bands in IR absorption spectra for HCl disolved in liquid $CO_{2}$ were measured. The multiple growth of fundamental band integral intensity and some decrease (by 20%) of overtone band intensity for HCl under phase transition gas-liquid solution were discovered. The mechanisms of the intensity formation for studied spectra are discussing. It was carried out the nonempiric quantum chemical calculations of intermolecular interactions in $HF-CO_{2}$ and $HCl-CO_{2}$ complexes. Calculated and experimental data on electrooptic parameters and intensities of IR absorption spectra for studied systems are comparing and discussing.
