Abstract

Applying femtosecond spectroscopic techniques numerous data have been obtained on photosynthetic antennae the structure of which is known with atomic resolution. To get a deeper understanding of the functionality of these pigment-protein complexes, in particular how structure is related to the sub-picosecond dynamics comparative simulations are indispensable. In utilizing the density matrix approach exciton motion among the chlorophyll (Chl) molecules and its triggering by protein vibrations can be investigated in detail /1, 2/.
