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
The static and transient fluorescence spectroscopy of 3-hydroxyflavone, 3HF, has been investigated as a function of deuteration of the 3-hydroxy group and the solvent. Small H/D isotope effects are observed for at least two of the simple rate constants for the excited-state dynamics. The isotope eff
Recently, the excited state proton transfer has been reported in jet-cooled methanol complex of 3-hydroxyflavone ( Dawes and Wallace. However, selective excitation of the methanol cluster bands longer than the origin band ( 356.12 nn 3-HF demonstrates that no excited state proton transfer takes plac
