Research Abstract

Electronic and vibrational spectroscopy has been applied to crystalline 3-hydroxyflavone derivatives and 2-(2-hydroxypheny)benzimidazole, and 7-hydroxyquinoline in a low-temperature glass matrix. We have found that photoisomerization dyanmics such as proton-transfer and charge-transfer in these molecular systems in the solid state are very different from that in the isolated states.
