| Abstract: | Enzymically generated triplet carbonyl compounds transfer energy to the fluorescent state of flavins as shown by the suppression of the carbonyl chemiphosphorescence and concomitant appearance of the flavin fluorescence. A Stern-Volmer analysis including the effect of the collisional quenching by a diene indicates that the transfer occurs by a long range process.The present results open the way to “photobiology without light”. |
