Abstract
Water vapor line broadening coefficients induced by carbon dioxide are important for different problems of atmospheric physics, astrophysics, and laser physics. Line widths of H2O–CO2 were computed by a semi-empirical method for rotational quantum numbers J from 0 till 20. The temperature dependence was investigated and the temperature exponents for every transition were calculated.
