Description

Reactivity and photochemistry of halide anions: atmospheric implications. Bromine and iodine are suspected to be responsible for most of the halogen-induced ozone loss in the stratosphere but are not currently included in atmospheric models due to a paucity of knowledge of the gas-phase chemistry and photochemistry of their anions and radicals. This project will develop and deploy advanced mass spectrometry and laser spectroscopy techniques to enable precision measurements of the reactions and photo-reactions of gas-phase iodide and bromide anions and their oxides. These state-of-the-art measurements of reaction kinetics and products will enable accurate chemical models that predict the impact of bromine and iodine chemistry on ozone levels and will inform future models for global climate..
