Note on the determination of the efficiency of the reaction N₂(A³Σ)+O(³P) to N₂+O(¹S)

Abstract

From the measurements of the 558 nm O(1S) to (1D) line and the 276 nm (0-6) nitrogen Vergard-Kaplan band emissions in a flowing apparatus. The authors show that the rate constant of the reaction N2(A3 Sigma )+O(3P) to N2(X)+O(1S) is given by ks=2.1*10-11 cm3 s-1. They solve numerically the set of coupled equations governing the N2(A 3 Sigma , v) and O(1S) concentration along the flow tube.
