Quenching of N2(A3Σu+) by O2, O, N, and H

Abstract

AbstractMetastable N2(A3Σu+), υ = 0, υ = 1, molecules are produced by a pulsed Tesla‐type discharge of a dilute N2/Ar gas mixture. Rate coefficients for quenching these metastable levels by O2, O, N, and H were obtained by time‐resolved emission measurements of the (0, 6) and (1, 5) Vegard–Kaplan bands. In units of cm3/mole · sec at 300°K and with an experimental uncertainty of ±20%, these rate coefficients for N2(A3Σu+) are Within the limits of error these coefficients apply to quenching N2(A3Σu+) υ′ = 1 as well.
