RED EMISSION FROM CHLOROPLASTS ELICITED BY ENZYME‐GENERATED TRIPLET ACETONE AND TRIPLET INDOLE‐3‐ALDEHYDE

Abstract
—Enzyme‐generated triplet acetone and triplet indole‐3‐aldehyde transfer energy very efficiently to chloroplasts, as indicated by the intensity of the sensitized red emission that is observed. The intermediacy of excited species of oxygen (1O2, O2, HO) has been excluded. Our results open the way for investigating energy transfer in architecturally organized systems in the absence of light.
