    • The storage of solar energy in energetically rich organic compounds represents the basis of life on earth and the related process is called photosynthesis. It starts with a primary charge separation in the photosynthetic reaction center. In most cases the initial excitation is supplied by light-harvesting antennae, which surround the reaction center to enlarge the cross-section for the capture of sunlight. There is a huge diversity of antenna complexes in bacteria and higher plants. For some of them the structure is known with an atomic resolution for details see, e.g, 3, 4, As it could be clarified in detail over the last three decades excitation energy transfer in photosynthetic systems takes place via Frenkel exciton mechanism

    • There have been attempts to compute the electronic energy level structure for such a complex of chlorophyll molecules embedded into the carrier proteins see references in [4, 18, However, such quantum chemical approaches have been successful only in part since the consideration of the whole carrier proteins is beyond present day computational capabilities. Moreover, a direct computation of the coupling of excitons to intrachlorophyll vibrations and to those of the surrounding protein is also hopeless at the moment. Consequently, an approach has to be chosen which is based on additional assumptions mainly related to the energy level structure of the chlorophylls and their mutual interaction. Concrete parameter values are fixed by a comparison of this model with different experimental results. This just underlines the importance of the presented model
