Excition theory of spectra and energy transfer in photosynthesis: spectral hole burning in the antenna of purple bacteria Original Research Article

A theory of hole burning in the antenna of photosynthetic purple bacteria has been developed. The theory is based on the model of excitation delocalization over the circular aggregate of pigment molecules (DCA model). A good agreement between the theoretical spectra and experimental hole profiles for purple bacteria was obtained. The advantages of the DCA model for interpretation of spectral and kinetic data are discussed.
