Abstract

Structural description of excitation migration in multireaction center light harvesting systems was illustrated. The approach was then applied to light harvesting in the trimeric form of cyanobacterial photosystem I (PSI). It was found that the excitation is shared between PDI monomers and the chlorophylls providing the strongest respective links were identified. It was suggested that on an average there is a nearly 40% chance of excitation cross transfer and trapping, indicating efficient coupling between monomers.
