STATISTICAL MODEL APPLIED TO THE REGION OF THE NU-3 FUNDAMENTAL OF CO2 AT 1200 DEGREES K

Abstract

A new method was developed to correlate the observed emissivity of a statistical band with the experimental parameters of the gas (pressure, optical path, etc.). Use is made of curves of growth for every frequency in the band and the method is applied to the region of the 4.3 micron bands of CO2 at 1200 K. Experimental results for CO2 are described, which were obtained by heating the gas in cells of different length in an electrical furnace. Good quantitative agreement is found with experimental results of other workers. It is shown that the statistical model predicts the emissivity correctly over wide range of pressure and optical path. The report of this work was published in the J. Opt. Soc. Amer., no. 3, 1963, and is not included here.
