Abstract
When nitric oxide is added to a flow of oxygen in helium which has passed through an electric discharge, O2(1Σ+ g) is produced. The main excitation process is the energy pooling reaction NO* 2+ O2(1Δg)→ NO2+ O2(1Σ+ g)(5) which has a rate coefficient in the range 2–6 × 1010 dm3 mol–1 s–1. NO* 2 is identified as the same state or states which lead to the air afterglow emission. The value of the rate constant for the reaction O2(1Δg)+ NO [graphic omitted] O2(3Σ– g)+ NO (7) has been measured as k7= 2.7 ± 0.6 × 104 dm3 mol–1 s–1 in agreement with earlier work.Keywords
