Abstract

Correlations of band absorption based on the Goody model for average spectral absorptivity and an arbitrary band structure model are presented for the 7.6-μ and 3.3-μ methane bands and the 15-μ, 4.3-μ, and 2.7-μ carbon dioxide bands. The correlation gives band absorption as a smooth function of path length, pressure, and temperature. Correlation parameters were obtained from data at temperatures of 300°K, 555°K, and 833°K in the case of CH4 and 300°K, 555°K, 833°K, 1110°K, and 1390°K in the case of CO2. Comparisons of the correlations with data of various investigators are presented.
