LASER-INDUCED PHOTO-DISSOCIATION OF HN3 AT 266 NM .2. REACTONS OF NH(1-DELTA) WITH HN3, HCL AND HYDROCARBON SPECIES

In the preceding paper it was shown that the 266 nm photodissociation of HN3 gives rise to NH fragments exclusively in the vibrationless a(1Δ) state with about 900 cm-1 of rotational energy. These fragments collisionally react with HN3 to produce NH2(2A1) in a chemiluminescent reaction. The time resolved chemiluminescence emission is used to determine the reaction rate for NH(1Δ) + HN3 → NH2(2A1) + N3(2Πg). The reaction rates of NH(1Δ) with several other species, HCl, CH4, C2H4, C3H6 and C6H12 are reported. Possible mechanisms for these reactions are considered. Condensed phase experiments are reported describing the addition reaction of NH(1Δ) with cyclohexane. © 1978.
