EXCITED STATES OF FLAVINE COENZYMES‐III. FLUORESCENCE AND PHOSPHORESCENCE EMISSIONS

Abstract

Abstract— Fluorescence and phosphorescence spectra of lumiflavine, riboflavine, FMN and FAD have been measured by continuous and flash excitation techniques. The differences in emission characteristics observed, show that the flavine side‐chains afect the singlet‐triplet transitions on which chemical and biological activity of flavine systems depend.
