Abstract

The averaged energy difference method was applied to calculate water vapor line broadening induced by hydrogen and helium pressure. Calculations were performed for wide ranges of rotational quantum numbers (J from 0 till 20 by the averaged energy difference method and J from 20 till 50 by interpolation of J-dependence), the spectral range is from 500 till 10 000 cm^-1. The temperature exponents were calculated for every mentioned line. Comparisons of the calculated line shape parameters with the literature values are made for H₂O-H₂, -Не colliding systems.
