Abstract

We report on the resonance Raman spectrum of the triplet excited state of 2- methoxy-naphthalene (3ROMe) generated by benzophenone (BP) triplet sensitization. A comparison of the time resolved resonance Raman (TR3) spectra of 3ROMe obtained by energy transfer with that of the spectrum obtained in the absence of BP reveals no change in vibrational frequencies due to weak charge transfer interaction, as expected for a triplet exciplex. It is observed from our computational studies and the experimental data that the unpaired electron in the * orbital of triplet state is more localized on the aromatic ring attached to the methoxy group.
