DETERMINATION OF THE SPONTANEOUS EMISSION PROBABILITIES AND THE COLLISION SELF-BROADENING COEFFICIENTS OF THE СО2 SPECTRAL LINES

Abstract

The technique of simultaneous determination of the spontaneous emission probabilities Аmn and the collision self-broadening coefficients γmn of the СО2 spectral lines is presented. The dependence of the absorption coefficient on the gas pressure, obtained for the СО210R22 line at temperature 300 K was measured. Using the data, the spontaneous emission probability Аmn and the collision self-broadening coefficient γmn were calculated.
