Excited-State Proton-Transfer Kinetics in 1-Naphthol, 1-Naphthol Sulfonates, and Organometallic Complexes [PDF]
, 1980 Upon photoexcitation many aromatic compounds are known to undergo ultrafast proton-transfer reactions in aqueous solution [1]. Picosecond spectroscopy offers the opportunity for modeling and understanding proton-transfer processes in solution by allowing direct measurements of proton-transfer kinetics to be carried out for broad classes of compounds ...
