Abstract

An improved method free from any fitting parameters is proposed and the package of computer programs is elaborated for 3-D classical trajectory simulation of pressure broadened vibration-rotation absorption bands contours of linear molecules. The calculations were carried out for a CO₂-Ar system with ab initio potential. An excellent agreement of theoretical results with data of absorption measurements in 4.3 micrometers far wing of CO₂ is obtained. The test of different trajectory models for interparticle collisions is presented.
