Abstract

Molecular structures of chlorophyll a aggregates have been studied. Spectroscopic properties of these aggregates have been studied by absorption and fluorescence spectroscopy in hydrocarbon solution at various temperatures. Observed spectroscopic shifts were interpreted in terms of simple exciton theory. Exciton splittings were estimated from computer optimized models of previously suggested Chl a aggregate structures.
