THE SPECTRAL ABSORPTION COEFFICIENT OF HEATED AIR

Abstract

That portion of the line absorption coefficient for heated air which depends only on the molecular band systems,i.e.,not on population numbers, has been calculated for each line in the frequency region of interest, with a total of over 150,000 lines tabulated on magnetic tape. With the results for the O2 Schumann-Runge system, a preliminary transport calculation has been completed for a slab of molecular oxygen. The effect of line widths on transmission is illustrated, and average transmissions are given as a function of frequency. The present results are compared with those of a previous calculation.
