Photochemistry of N2O∗·H2O complexes produced in supersonic jets

초록

We have studied 193 nm photodissociation of N<inf>2</inf>O·H<inf>2</inf>O complexes produced in a supersonic jet resulting in the reactant-pair reaction N<inf>2</inf>O·H<inf>2</inf>O +hv → 2OH + N<inf>2</inf>. Measured internal energy, and spin-orbit and Γ-doublet distributions in OH by laser induced fluorescnce suggest a reaction scheme much different from the corresponding bimolecular reaction, O(1D) + H<inf>2</inf>O → 2OH, observed in bulb experiments. The reaction should occur indirectly with early escape of N<inf>2</inf> and proceed slowly in a relatively long-lived intermediate O·H<inf>2</inf>O. © 1994 SPIE. All rights reserved.
