Abstract
Using a tunable CO2 laser, unsaturated absorption coefficients in pure CO2 and binary CO2 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) CO2 spectral lines of the 1000-0001 transition at 300–700 K. The coefficients of the collisional broadening of the CO2 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.
