Radical-water complexes in Earth's atmosphere

In the atmosphere, many chemical processes are controlled by open-shell rad ical species. While these species are present in relatively small number de nsities, they initiate many of the cycles that control the chemistry of the atmosphere. The purpose of this Account is to examine recent studies of ra dical-water complexes that are composed of atmospherically important specie s. We hope this Account will provide a report on the status of this topical field, while encouraging new research directions.
