A simple technique for the measurement of rates of deactivation of N2 A 3? + u

Abstract

By subjecting gas mixtures containing NO, at low pressures, and N₂ to a short duration flash of ultra-violet radiation, it was demonstrated from the delayed NOγ-emission that N₂A³Σ⁺ _u is produced in the quenching of NOC²Π(v= 0) by N₂. The rate coefficient for removal of N₂A³Σ⁺ _u by H₂O was recorded as 5.5 (±3.0)× 10^–14 cm³ molecule^–1 s^–1.
