Gas phase chemistry of chlorine nitrate
Abstract
Chlorine nitrate (ClONO{sub 2}) is a reservoir of both ClO{sub x} and NO{sub x} radicals in Earth`s stratosphere, and its decomposition is important in determining the abundance of stratospheric ozone. We present experimental and theoretical studies that explore the mechanisms and dynamics of processes leading to ClONO{sub 2} destruction in the stratosphere. Molecular beam photodissociation experiments have been performed to determine the decomposition pathways of ClONO{sub 2} upon excitation at 308 nm and to explore the possibility of a long-lived excited state. We have also investigated the reaction of chlorine nitrate with chloride ions Cl{sup -} in the gas phase. The gas phase ionic reaction may elucidate ionic mechanisms of heterogeneous reactions occurring on the surfaces of Polar Stratospheric Cloud particles and also raise doubts about proposed schemes to mitigate ozone depletion by electrifying the stratosphere.
