Abstract
The low-dose radiolysis of N2-O2 mixtures has been investigated at 101 kPa and 299 K. Measurement of the yield for NO and NO2 as a function of the N2 mole fraction has been analyzed to give a G(N) value of 7.3 ± 1.5 for the yield of N(4S) and N(2D,2P) atoms for the radiolysis of N2. Computer simulation of the neutral N2O2 chemistry under radiolytic conditions showed that N atoms are predominately formed in a metastable state. Predissociation of N2 electronic states in the 12 to 16 eV range is responsible for the production of metastable atomic N(2D) and N(2P) atoms.
