Additional Observations of Chemiluminescence in Mixtures of Atomic Oxygen and Nitrogen

摘要

Reinvestigation of the nitrogen afterglow using specially purified nitrogen indicates that an intermediary or precursor in the reaction path leading from free nitrogen atoms to the emission state is quenched by N2but not by He. The O2atmospheric bands and the O I 5577hyphen;Aring; line were not detected at the NO null titration point. The O2Herzberg bands are independent of pressure in both N2and 1 N2in He systems, indicating that equilibrium exists between the radiative state and free atomic oxygen.
