Abstract— The absorption and fluorescence emission spectra of lumiflavin have been studied in nonaqueous solvents different polarity. corrected show apparent mirror symmetry to the longest wavelength maximum. In view high molar extinction coefficient maximum spectra, constant polarization across it dioxane values quantum yields Buorescence, τ→τ* character corresponding electronic transition was proposed. Roughly linear correlation found between energies on one hand, polarity expressed Kosower's ‘Z’ (excepting acetic acid) other. preliminary experiments that acid is strongly photodecomposed by monochromatic(436 nm) light.
