Abstract : The migration and trapping of excitation quanta in photosynthetic units are treated as a problem of the transport of localized excitons through molecular networks. One, two, and three dimensional networks are treated as distinct cases. For the most part, attention is restricted to regular lattices, and all but nearest neighbor interactions are neglected. The latter are characterized by a single rate constant for ordinary pairs of molecules in the network, and by a possibly distinct rate between an ordinary molecule and a trapping center, or trap. It is pointed out that results for those finite networks explicitly considered apply also to infinite systems with periodic traps.
