Abstract : Simplified equations are developed for computing the emissivity of the carbon dioxide 4.3 micron band. The harmonic oscillator model is assumed in computing line intensities, but anharmonicity is considered in computing the frequencies of emitted radiation. Calculated values are presented for temperatures ranging from 300 to 3000 K, from which emissivities may be readily computed for a given pressure and optical path in both the weak line and strong line approximations. Comparisons are made with published experimental data using the weak line approximation, and in several cases, the strong line approximation. A mixed strong lineweak line approximation is also shown. The results are shown to be in reasonable agreement with published experimental data and in definite disagreement with other theoretical calculations. (Author)
