Photochemical reaction of harmalol. Part 2. Electronic spectra

Electronic spectra (absorption, emission and excitation fluorescence spectra) of harmalol in organic solvents have been recorded. The unusual behaviour of this alkaloid has been studied by excited state proton transfer from organic solvents. The effect of the presence of water in the organic media o...
