Abstract

Abstract Two methods, one based on non-linear least squares and one based on an approximation, are described for determining the rotational temperature of diatomic molecules from absorption spectra measured with moderate resolution. Experimental tests with CO and CO/air mixtures gave good results. The importance of line widths and instrumental distortions is emphasized.
