A theory of the IR radiation (2-20 microns) of the upper atmosphere (90-250 km height) has been developed. It includes the calculation of concentrations and temperatures as well as the analysis of atomic and molecular level population kinetics. Various excitation and quenching processes are analyzed. Results are given for the following bands: NO (5.3 microns), NO(+) (4.3 microns), CO (4.7 microns), (N-14) (N-15) (4.4 microns), CO2 (4.3 and 15 microns), H2O (2.7 and 6.3 microns), N2O (4.5, 7.8, and 17 microns), and O3 (9.6 and 14.4 microns). The energy aspect of the problem is discussed. It is found that at a height of 120 km the intensity in the region from 2 to 20 microns is 3 to 10 times greater than that of the 63-micron line of atomic oxygen. A comparison of theory with experiment yields satisfactory agreement. Correlations between the intensities in the IR bands and emissions in the visible and UV spectra are considered.
