Abstract

Optical line shapes were calculated for photosynthetic light-harvesting complexes using general formalism of exciton-phonon interaction in molecular crystals. We analyzed the quasi one-dimensional molecular systems such as circular bacteriochlorophyll (BChl) aggregates (LH1 and LH2 complexes of purple bacteria). The theory is valid for arbitrary strong linear electron-phonon coupling covering the delocalized (free) exciton as well as localized (self- trapped) exciton limits. The theory is used to analyze the recent hole-burning data on the light- harvesting antennae of purple bacteria.
