In a new experimental approach (Evanescent Wave Photocatalysis), we localize laser photoexcitation in a narrow boundary gas layer just above an interface. All the excited molecules can reach the surface before the relaxation. Approaching the surface, these molecules will naturally experience strong acceleration and alignment. The energy of the excitation is likely to be converted to kinetic motion along the reaction coordinate for chemical adsorption. While recombination chemical reactions in a gas phase require participation of a third body, this strong limitation on the reaction rates is removed upon interaction with a surface. First experimental results indicate an opening for investigations of a new, previously unexplored domain in photochemistry.
