title: Dynamic and structural properties of aqueous arsenic solutions.
abstract: Aqueous arsenic solutions are important in geochemistry, environmental chemistry, and biochemistry. Thus, studies of arsenic solutions that probe the structure of the hydrated arsenic ion and the behavior of water around As ions have wide-ranging implications. The mechanisms for water dissociation around three arsenic ions (see picture) and structural details of the resulting aqueous complexes are presented.
