Abstract

This report contains an outline of some of the experimental measurements and theoretical considerations which are required for the calculation of the emissivity of nitric oxide. Because of lack of suitable apparatus, the experimental part of the program was restricted to the determination of apparent absorption coefficients for the fundamental vibration-rotation band of nitric oxide. Theoretical calculations of emissivity were originally suggested by Dr. Martin Summerfield. The present calculations were made by the use of an approximate procedure which has been developed recently at the Jet Propulsion Laboratory by S. S. Penner for the determination of the emissivity of pure diatomic gases. The results presented in this report facilitate making approximate estimates of the emissivity of nitric oxide as a function of temperature and optical density. For these emissivity calculations it is recommended to correct the experimentally determined apparent absorption coefficients by analogy with available data for carbon monoxide.
