报告人简介：

Prof. Per E. M. Siegbahn was born in Stockholm, Sweden. He did his undergraduate studies at Uppsala University and received his Ph.D. degree at Stockholm University in 1973 (with Bjorn Roos). He was a postdoctoral fellow at the University of California, Berkeley (with Henry F. Schaefer, III), and at IBM, San Jose (with Bowen Liu). He returned to Stockholm and has remained ever since. He has published over 300 papers in international journals, including Chem. Rev., Acc. Chem. Res., Proc. Natl. Acad. Sci. U.S.A., Angew. Chem. Int. Ed., and J. Am. Chem. Soc.

报告内容：

Methods and models have been developed during the past twenty years that are capable of solving mechanistic questions for redox-active enzymes. The strategy adapted has been to base all conclusions on experience, without pre-assumptions. A very large number of model calculations were performed to test the strategy chosen, by far more than by any other group in this area of quantum chemistry. Some of the most difficult problems in biochemistry has by now been solved, most notable the one of water oxidation in Photosystem II. But for many other enzymes the calculations have given mechanisms, never suggested before, which only later on have been confirmed by experiments.
