Abstract:

The influence of two factors on the contour of an absorption line of water vapor molecule in a mixture with helium, argon, krypton, and xenon is studied: the dependence of the broadening coefficients g and shifting coefficient δ on the velocity va of the absorbing H2O molecule (wind effect) and the change in the velocity of H2O upon collision with these atoms. Three absorption lines of H2O molecule from ν+ ν+ ν3 band with different rotational quantum numbers of the initial quantum state were chosen for the study.

Keywords:

line profile, wind effect, Н2О, He, Ar, Kr, Xe
