Abstract

Results of an experimental determination of low resolution spectral absorptivities of carbon dioxide, carbon monoxide and mixtures of these gases at total pressures from 0.33 to 10 atmospheres, temperatures from 293 to 1200 K and a range of mole fractions are reported. An optical path length of 158 cms. Was used at room temperature and one of 12 eras, at that and higher temperature Optical densities ranged from 4 to 1580 atms. cms. Spectral measurements are compared with published experimental data. Band emissivities for the 4.3, 2.7, 2.0 and 1.6 micron bands of carbon dioxide and U.7 and 2.35 micron bands of CO obtained from spectral measurements, are presented. Correlations of band emissivities with optical density, total pressure, and temperature, using extended spectral models and an empirical band model, are given. Theoretical estimates of band overlap corrections were made for the major bands of carbon dioxide- and carbon monoxide in the 4 to 5 micron region. These are compared with values derived from experimental data. Charts for band overlap correction are presented.
