Abstract : Chemical kinetic calculations are presented which describe the chemistry of nitrogen oxides and ozone in D-region air bombarded by an intense pulse of X-rays as would be produced by nuclear explosions. Relatively latetime behavior is emphasized; early deionization processes are treated in a summary fashion. Special attention is given to the reactions of excited species, which have not been included previously, but which greatly affect the yields of NO, NO2, and O3. Results are given for various altitudes, bombardment intensities, and both day and night conditions. The reactions that mainly control the chemistry are identified, and the effects of the excited species are summarized. (Author)
