title: Delayed fluorescence and phosphorescence of flavomononucleotide stabilized by poly(vinyl alcohol) matrix.
abstract: Phosphorescence spectra at 103 K and delayed fluorescence and phosphorescence spectra at 296 K of flavomononucleotide (FMN) stabilized by poly(vinyl alcohol) PVA matrix have been measured. At 103 K the FMN monomer and excimer exhibit phosphorescence bands at about 620 and 640 nm, respectively. At 295 K the delayed fluorescence and phosphorescence of the FMN excimer exist together, revealing that FMN in the excited triplet state is an energetically well-isolated molecular complex which may play an important role in photobiological reactions.
