Reaction of chlorine nitrate with protonated water clusters: a model for heterogeneous reactions on polar stratospheric clouds


We investigated the reactions of small protonated water clusters, H_3O^+(H_2O)_m, with chlorine nitrate, ClONO_2, to elucidate the molecular mechanism for the heterogeneous reaction of chlorine nitrate with ice. The ionic reaction products were various forms of protonated nitric acid, NO_2^+(H_2O)_m, m = 0, 1, 2. These products are analogous to products previously reported in the literature for the neutral reaction occurring on ice surfaces. Our results support the hypothesis that the heterogeneous reaction is acid-catalyzed.
