Collisional Deactivation of NH2(Ã 2A1)

Abstract

${\mathrm{NH}}_2{\mathrm{(Ã\hspace{0.17em}}}^2{A}_1)$ was produced by photolysis of ammonia in the vacuum ultraviolet. Deactivation rates of this radical were measured by the quenching of fluorescence in NH₃, CH₄, H₂, N₂, He, Ne, Ar, Kr, Xe. An estimate of the lifetime of spontaneous radiative decay of 0.8×10⁻⁵ sec is suggested. Application of the results to the dynamics of the Jovian atmosphere is reported.
