Abstract

We discuss experimental results from spectroscopic and kinetic investigations of the reaction sequence starting with NCI₃ + H. Through a series of abstraction reactions, NCI (a¹Δ) is produced. We have used sensitive optical emission diagnostics and have observed both [NCI(a¹Δ)]and [NCI(b¹Σ)] produced by this reaction. Upon addition of HI to the flow, the reaction of H + HI produced iodine atoms that were pumped to the excited I(²P_1/2) state, and we observed strong emission from the I atom ²P _1/2 -> ²P_3/2 transition at 1.315 μm. With a tunable diode laser we probed the I atom transition and observed significant transfer of population from ground state (²P_3/2) to the excited state (²P_1/2) and have observed optical transparency within the iodine atom energy level manifold.
