We have investigated excitation energy transfer(EET) in the antenna system of photosynthetic bacteria. The antenna system consists of complexes where chromophores aggregate. And in the complexes, exciton levels are formed. We proposed a new formula to elucidate the mechanism of the EET between these aggregates of chromophores. When the distance between the aggregates is smaller than their sizes, EET occurs through optical forbidden states. Using Green's function method, the EET rate between antenna complexes is estimated.
