Atmospheric Photochemistry at Aqueous and “Wet” Surfaces

There are often pronounced environmental effects on photochemical processes, due to the influence that solvation may exert on reaction energetics and the electronic structure of chromophores.Tthere has been a lot of research on aqueous phase photochemistry of atmospheric relevance; often the chemistry is modified significantly from its gas phase counterpart. The aqueous surface represents a distinctive environment at which photochemistry may occur: chromophoric species present at the interface are only partly solvated and the presence of realistic impurities may further influence the available photochemical pathways. I will discuss some recent work which investigates how the nature of the aqueous (or wetted organic) surface alters the photochemistry of both organic and inorganic species present there.
