The excited state dynamics of jet-cooled 3-hydroxyflavone and its methanol complexes have been studied using both timeresolved dynamic measurements and excitation and emission spectroscopy. Methanol complexation has a significant effect on the molecule's emission spectrum and fluorescent lifetime, a

Jet cooled fluorescence lifetimes following excitation of S I origins have been measured for 4-hydroxyindole. The subnanosecond values obtained are anomalous compared to other substituted indoles, in particular 5-hydroxyindole. The short lifetimes are most likely related to excited state tautomerism

Molecular orbital calculations reveal that the keto tautomer of HOCHCHNHNCHz, unlike the enol, does not represent a minimum in the ground state proton transfer potential. Excitation to the first excited singlet or triplet state leads to a rapid and barrierless transfer to the keto which becomes stro
