Notes:
Metastable 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 \documentclass{article}\pagestyle{empty}\begin{document}$$k_{{\rm O2}} = 2.9 \times 10^{- 12}$$\end{document} \documentclass{article}\pagestyle{empty}\begin{document}$$k_{{\rm O}} = 1.5 \times 10^{- 11}$$\end{document} \documentclass{article}\pagestyle{empty}\begin{document}$$k_{{\rm N}} = 4.8 \times 10^{- 11}$$\end{document} \documentclass{article}\pagestyle{empty}\begin{document}$$k_{{\rm H}} = 3.5 \times 10^{- 12}$$\end{document}Within the limits of error these coefficients apply to quenching N2(A3Σu+) υ′ = 1 as well.
