Picosecond spectroscopy of intermolecular proton phototransfer

A study was made of intermolecular phototransfer of a proton in solutions of 3-methoxybenzanthrone in benzene and in tetrahydrofuran (THF) with toluenesulfonic acid or 3-fluoroacetic acid. The elementary constants were determined in the case of THF solutions. An analysis was made of the possibility of using proton phototransfer in construction of efficient fluorescence light concentrators and dye lasers.
