Abstract

IR absorption in the region of forbidden molecular transitions is usually considered to be determined by collision-induced mechanisms. Most frequently the absence of any structural features superimposed on the collision-induced background is interpreted as an evidence of the negligible contribution of the bound dimer states. However, in some cases the most important statistical weight belongs to metastable states, rather than bound ones. In general, the dimer molecules highly excited above the dissociation limit have to be considered as metastable molecules. The contribution of metastable molecules to collision-induced absorption must correspond to the portion of the phase-space they occupy and therefore could be considerable. The goal of this paper is to interpret the collision-induced absorption in compressed carbon monoxide as a sum of bound and quasibound dimeric contributions.
