Paper Abstract

Pressure dependences of carbon dioxide absorption coefficients for several CO laser transitions from 1850 to 1920 cm-1 are measured. A comparison with the calculations (HITRAN-91) has been made. The calculated data for the Q-branch (1880.994 cm-1) of the (2020)I-0110 CO2 band are 20% lower than the measured ones. In the P-branch (1932.472 cm-1) of the (1110) -00 degree(s)0) CO2 band experimental absorption coefficients appeared to be 10 - 20% lower than the theoretical ones. The intensity and the self-broadening coefficient are determined for the P46 line of the (1110)II-00 degree(s)0 carbon dioxide band.
