Abstract
Theoretical broadening coefficients of rotation vibration water vapor lines induced by hydrogen pressure are given. The averaged frequency method has been used to calculate line widths. Calculations have been performed for a wide interval of rotational quantum numbers in the spectral region from 500 to 10 000 cm-1. Line widths have been computed by the averaged frequency method for rotation quantum number J from 0 to 20, data have been obtained by interpolation of J- dependence for J from 20 to 50. Temperature exponents for line widths have been defined.
