Abstract
Information on the spectral absorptance of various gaseous components which are combustion products of fuels is needed for the solution of many practical problems associated with the transfer of the radiation of a flame into the atmosphere and radiative heat transfer in power plants. Investigations of the influence of the temperature on the formation of the IR absorption and emission spectra of gaseous components are of interest in themselves. Advances in theoretical spectroscopy will make it possible to utilize the results of quantumchemical calculations of the parameters of lines [i, 2] for the solution of radiation-transfer problems in media with nonuniform structural characteristics and chemical compositions [3]. At the same time, the significant errors in the calculation of the intensities of lines at high temperatures calls for their absolute normalization, which must be carried out with respect to the integral intensities of vibration--rotation (VR) bands and with respect to the intensities of lines in narrow portions of the spectrum measuring A = 5-25 cm -I.
