Paper 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(2P1/2) state, and we observed strong emission from the I atom 2P 1/2 -> 2P3/2 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 (2P3/2) to the excited state (2P1/2) and have observed optical transparency within the iodine atom energy level manifold.
