Abstract

The fluorescence properties of 3-hydroxyflavone isolated in solid Ar at 15 K were investigated. Upon electronic excitation the mols. undergo rapid intramol. H+ transfer. No fluorescence from the excited state of the normal form of the mol. was detected. Perturbations due to H-bonding impurities which produce serious exptl. problems in hydrocarbon glasses are largely suppressed in Ar matrixes. The ...
