The kinetics of reactions involving the ground-state azide radical, N3 (X2Πg, have been investigated in a discharge-flow system using mass spectrometric detection with molecular-beam sampling. The following rateconstants have been determined at 295K: Cl + N3Cl → Cl2 + N3,k295 = (1.78 ± 0.26) × 10−12 cm3 s−1 (1σ): N3 + NO → N2O + N2, k295 = (1.19 ± 0.31) × 10.−12 cm3 s−1 (1σ).

A kinetics study of the NCl radical at 295 K has been carried out in a discharge–flow system using mass-spectrometric detection with molecular-beam sampling. NCl radicals were generated by the reaction of Cl atoms with N3Cl: Cl + N3Cl → N3+ Cl2, Cl + N3→ NCl(b1∑+), (a1Δ), (X3∑–)+ N2.

near-threshold photoionization of N3 photofragments produced by laser photodissociation of ClN3 at 248nm. The time of flight of recoiling N3 is used to resolve two photochemical channels producingN3, which exhibit different translational energy release. The two forms of N3 resolved in this way exhibit different photoionizationthresholds, consistent with their assignment to linear (X 2pi(g)) and cyclic N3.

The time decay of N2 (A3σ +u) produced by pulsed photolysis of CIN3 at 193 nm exhibits two components, a fast decay corresponding to pseudo-first-order quenching by CIN3 and a much slower decay corresponding to a chain process in which N2(A3Σ+u) is regenerated. The rate constant for N2(A3Σ+u) quenching by CIN3 is (5.6±0.6)×10−11 cm3 s−1. The quantum yield for production of N2(A3Σ+u) by the photolysis

formation. Products of the unimolecular dissociation of HEF-N(3) are observed in the mz = 14(N(+)) and mz = 28(N(2) (+)) data. Anisotropy parameters were determined for the primary channels to be beta = -0.3 for the NCl forming channel and beta = 1.7 and beta = 0.4 for the linear N(3) and HEF-N(3) forming channels, respectively. There is additional evidence for secondary photodissociation of N(3) and of NCl
