Paper Abstract

At pressures about 1 atm well separated rotational-vibrational lines of a gas have Lorentzian shapes. When the lines superimpose the absorption coefficient deviations from the sum of Lorentzian contours are often observed especially in tine wings. These deviations are usually explained by the line mixing effects which can be calculated for the central parts of bands using the impact approximat ion. In this approximat ion the transformat ion of the band shape with pressure is determined by the relaxation Γ-matrix structure.
