Ebook: Antennas and Reaction Centers of Photosynthetic Bacteria: Structure, Interactions and Dynamics

The workshop on "Antennas and Reaction Centers of Photosynthetic Bac­ teria" was held at Feldafing, Bavaria (F. R. G. )' March 23-25, 1985. This workshop focussed on primary processes with emphasis on structure, inter­ actions and dynamics. It assessed structural, spectroscopic and dynamic data which have accumulated recently, providing an overview of the mech­ anism of the acquisition, storage and useful disposal of energy in bacterial photosynthesis. This volume is a record of the invited papers presented at the workshop. The material was organized into five sections: I. Antennas: Structure and Energy Transfer II. Reaction Centers: Structure and Interactions III. Electron Transfer: Theory and Model Systems IV. Reaction Cen,ters: Structure and Dynamics V. Model Systems on Function of Antennas and Reaction Centers I would like to express my gratitude to all the participants in the work­ shop for their contributions, and to the authors for the timely preparation of their manuscripts. I am indebted to the members of the organizing committee, Professors Sighart F. Fischer and Hugo Scheer for their most valuable assistance and advice. The workshop would not have been so successful without the help of my secretary, Frau Petra KahlfuB, and my coworkers in its organization. I thank Frau KahlfuB particularly also for her assistance in the preparation of these proceedings. The workshop was organized under the auspices of the Technical Uni­ versity of Munich, the Max-Planck-Society and the University of Munich.
