Abstract

The fluorescence of 2,5-bis(benzothiazolyl)hydroquinone was studied for isolated mols. cooled in a supersonic free neon jet. It consists of a strongly Stokes-shifted fluorescence band, and it is assigned to the mol. which is formed by excited-state intramol. proton transfer. The fluorescence excitation spectrum shows a progression in a 114-cm-1 vibrational mode of the excited state. The obsd. ...
