Deactivation of Vibrationally-Excited NO and CO2 by O-Atoms.
Abstract
Spectral measurements of the limb radiation of the earth have shown that emissions from the NO(v=1) and CO2(0l (1)0) states dominate the nighttime radiance seen at long wavelengths. At the high altitudes of the thermosphere, the deactivation of the aforementioned molecules helps regulate the temperature. A knowledge of the kinetics of deactivation of these molecules is therefore needed to accurately model the temperature of the thermosphere. Sharma and coworkers have developed a procedure to invert the profiles of the limb emissions to determine the vertical distributions of local atmospheric properties. This procedure can be used to monitor local NO, NO(v=1), CO2 and O densities as well as translational temperatures. They have shown the inversion procedure is sensitive to the rate of the reaction for deactivation of NO(v=1) and CO2(01(1)0) by O atoms. jg p.6
