摘要：

Unsaturated absorption coefficients are measured using a tunable CO2 laser in pure CO2 and CO2:O-2 = 1:2 and CO2:N-2 = 1:2 gas mixtures at the central frequencies of the R(8), R(22), P(8), P(22), and P(36) CO2 10(0)0-00(0)1 transition lines under a pressure of 100 Torr in the temperature range 300-700 K. The collisional broadening coefficients of the CO2 spectral lines by O-2 and N-2 are obtained. The temperature dependences of these coefficients are approximated by power functions with two different exponents.
