Progress in Modeling of Ion Effects at the Vapor/Water Interface

The behavior of halide salts at the vapor/water interface has been the focus of a tremendous amount of work in the past ten years. A molecular view of the interface has been introduced with the observation that large anions have some affinity for the interface, but a quantitative description of the driving forces that determine ion adsorption or repulsion at the interface is still missing. This review discusses recent developments that are based on classical and quantum-chemical molecular simulations as well as developments that are based on simple potential models.
