    Abstract

    The influence exerted on the H2O-molecule absorption line profiles in the H2O-He, H2O-Ar, and H2O-Kr systems by two factors - the dependence of broadening coefficient γ on velocity ν a of the absorbing H2O molecule (wind effect) and the collision-induced change in the H2O molecule velocity - is studied. Three H2O molecule absorption lines of the ν 2 band, which are formed by transitions from energy levels with different rotational quantum numbers J and K a, are chosen for investigations.
