Abstract We measured the dependence of the absorption, coefficient on the pressure for the vibrational-rotational transition P20 (00 °1–10 °0) in CO2 using a CO2 laser as a light source. We consider the question of the systematic error due to the contribution of impact broadening, when finding the probability from the experimental absorption. The refined value of the transition probability A 10 °0.20 00 °1.19 =0.169 sec−1. We obtain the values of the impact half-widths for collisions of the type CO2-CO2, CO2-N2, CO2-He, the values of which at J=300 °K are respectively 3.28, 2.74, and 2.27 MHz/torr.
