摘要：

2-(2'-hydroxy-5'-methylphenyl)benzotriazole (TIN) and 2-(2'-hydroxyphenyl)benzothiazole (HBT) are compared in this work with respect to their photoinduced intramolecular proton transfer reaction cycle in single crystal environment. Stationary and ps time-resolved optical spectroscopy is applied between 5 and 300 K. The enol emission and the keto O-O origin are detected for the first time. For both compounds complete energy level schemes are deduced. Temperature dependent reaction dynamics are discussed.
