INTRAMOLECULAR PROTON-TRANSFER AND EXCITED-STATE RELAXATION IN 2-(2-HYDROXYPHENYL)BENZOTHIAZOLE Academic Article

abstract

• The excited state vibrational and conformational relaxation of 2-(2-hydroxyphenyl)benzothiazole in solution has been studied as a function of temperature by means of picosecond spectroscopy, using a streak camera with <5-ps resolution. Three distinct relaxation processes were identified: (a) intramolecular proton transfer producing a cis-keto tautomer occurring within 5 ps from T = 4 to 300 K; (b) vibrational energy redistribution and/or relaxation into the medium at a rate of 10 s'1 at 4 K and increasing rapidly with temperature; (c) radiationless decay (102-103 ps) induced by large amplitude torsional motion in solution at T > 200 K. 1980, American Chemical Society.
