Radiolysis of Nitrogen -- Oxygen Mixtures

The products of radiolysis of a Ng—Og mixture include NOg, NgO, NO, and ozone. The yields of these products depend on pressure and mixture composition. The correlation between the energy yields of the radiation-chemical formation of ozone and of nitrogen dioxide in the Ng—Og system has been studied earlier [109]. The changes in G(NOg) and G(03) as a function of mixture composition are shown in Table 13. 

Nitrogen oxides (NgO, NO, NO2) have been found to form in ion-molecule reactions of N and NJ with O2, 0 , and of OJ with N2 [418]. 

The contribution of neutral active species to nitrogen oxidation is predominantly characterized by the following processes [387] 

Reactions involving excited ions and excited neutral species also seem to be of certain importance in the radiolysis of N2—O2 mixtures. The data on the irradiation of N2—O2 mixtures with 6.66 eV photons reveal the contribution of excited molecules to nitrogen oxidation [227].
