APPROXIMATIVE BAND ABSORPTION AND TOTAL EMISSIVITY CALCULATIONS FOR H2O,

Abstract

A highly simplified procedure, utilizing symmetrical band contours and intensity estimates derived from harmonic oscillator approximations, may be used to calculate band emissivities for H2O at sufficiently high pressures where the rotational fine structure has been removed. Agreement with experimental data is excellent. The empirically determined dependence of total emissivities on the partial pressure of water vapor, at constant total pressure, may be accounted for quantitatively by using a model of randomly distributed dispersion lines falling in the square root region of the curves of growth.
