Computer simulation of proton solvation and transport in aqueous and biomolecular systems.
The excess proton in aqueous media is critical to many aspects of chemistry, biology, and materials science. This species is at the heart of the most elementary of chemical (e.g., acid-base) and biological (e.g., bioenergetics) concepts, yet to this day, it remains mysterious, surprising, and often misunderstood. In this Account, our efforts to describe excess proton solvation and transport through computer modeling and simulation will be described. Results will be summarized for several important systems, as obtained from the multistate empirical valence bond (MS-EVB) approach, which allows for the explicit treatment of (Grotthuss) proton shuttling and charge delocalization.
