This chapter presents a personal historical perspective of the role of carotenoids in photosynthesis. It leads the reader into the early literature on the carotenoids and photosynthesis that are related to the discoveries on the excitation energy transfer and, to a lesser extent, on photoprotection. Excitation energy transfer from the carotenoid fucoxanthin to chlorophyll (Chi) a was shown first in the diatoms by H. Dutton, W. M. Manning and... 

Measurements on the action spectra of photosynthesis do not distinguish between the direct photochemistry by the carotenoids versus that by Chi a after excitation energy transfer from them to the Chls. This distinction is possible only from measurements on excitation energy transfer.

Photosynthesis is a natural energy conversion system that converts solar energy into chemical energy, the primary processes of which are a cascade of photoinduced excitation energy transfer to the reaction center GiC) and the subsequent rapid electron transfer to generate charge-separated state. Over the past decades, a series of significant results have been obtained for the smdy of photosynthesis (1) The stracture of the protein subunits in the photosynthetic RC has been ascertained. 

If the conditions for Forster transfer are not applicable, then the theory must be extended. There is recently experimental evidence that coherent energy transfer participates in photosynthesis [74, 75], In this case, the participating molecules are very close together. The excited state of the donor does not completely relax to the Boltzmann distribution before the energy can be shared with the acceptor, and the transfer can no longer be described by a Forster mechanism. We will not discuss this case. There has been active discussion of coherent transfer and very strong interactions in the literature for a longer time [69], and references can be found in some more recent papers [70-72, 76, 77],...
