Abstract

Proton-transfer reaction (PTR) of the jet-cooled 1-azacarbazole (1-AC) dimer has been studied by directly measuring, in real time, the fluorescence intensity from the precursor dimer and from the tautomer formed in the excited-state reaction process after exciting various intermolecular vibrational levels of the dimer. For the vibrational levels of the 1-AC dimer examined here, PTR is found to be predominant in the overall decay process. The rate of PTR is strongly dependent on the vibrational mode and is enhanced pronouncedly by excitation of the intermolecular symmetric-stretching vibration in the hydrogen bond.
