Abstract
An explanation of the excited-state structure of the FMO (Fenna-Matthe ws-Olson) complex of Prosthecochloris aestuarii is given from the poin t of view that the dipole-dipole interactions among the bacteriochloro phylls of the unaggregated C-3 symmetric trimers observed in the cyrst alline state are mainly responsible for the key features of the ''line ar'' absorption characteristics (absorption, linear dichroism, and sin glet-triplet absorption difference) in the Q(y) region.
