Abstract

The form of the fluorescence decay function from the light harvesting system of photosynthetic organisms has now been determined quite accurately by low-intensity synchronously pumped dye laser excitation coupled with single photon counting detection. Several groups [1,2,3] have found it necessary to use a sum of three exponential decay components (eq. 1) to fit the decay curves of both green plants and algae.
