Using a tunable CO{sub 2} laser, unsaturated absorption coefficients in pure CO{sub 2} and binary CO{sub 2} gas mixtures with inert gases He, Ar, Kr, and Xe in a 1 : 2 ratio at 100 Torr were measured at the central frequencies of the R(8), R(22), P(8), P(22), and P(32) CO{sub 2} spectral lines of the 10{sup 0}0-00{sup 0}1 transition at 300–700 K. The coefficients of the collisional broadening of the CO{sub 2} spectral lines by He, Ar, Kr, and Xe are determined. The obtained temperature dependences of the collisional broadening coefficients are approximated by power functions with two different degrees.
