The femtosecond kinetics associated with intramolecular proton transfer in the electronically excited state of aromatic molecules is investigated. The initial enol structure of 2-(2'-hydroxyphenyl)benzothiazole (HBT) is excited by a femtosecond UV pulse at 3 15 nm and the risetime of the emission of
Excited-state proton transfer in 2-(2'-hydroxyphenyl)benzothiaxole (HBT) dissolved in pyridine is investigated. New absorptions and fluorescence bands are detected after addition of water or NaOH to the solution. The spectra are identical to the HBT anion absorption and fluorescence. Picosecond spec
