Raman excitation profiles, fluorescence spectra and excited state proton transfer of solid 1.8 dihydroxyanthraquinone at 8 K

Abstract

The single crystal fluorescence spectra as well as the Raman spectra and excitation profiles of solid 1.8 dihydroxyanthraquinone have been measured. Four electronic transitions in the visible range were found: a π—π* active in absorption, a Franck—Condon absorption emission active transition and two emissions due to excited state proton and Hatom transferred configurations.
