Abstract
The technique and the results of the determination of the partial pressure of carbon dioxide and its temperature in a vibrationally equilibrium gas mixture CO2 : N2 at a pressure that provides for the Lorentz contour of the absorption line and on the basis of the spectral distribution of the unsaturated absorption coefficient at lines of 100-0001 transition of a tunable CO2 laser are presented.
