Walter Thiel Edit Profile

researcher , chemistry educator

Walter Thiel, German chemistry educator, researcher. Heisenberg fellow German Research Foundation (Deutsche Forschungsgemeinschaft), 1982; recipient Alfried-Krupp-Förderpreis, Krupp-Stiftung, 1988.


Thiel, Walter was born on March 7, 1949 in Treysa, Hessen, Germany. Son of Karl and Erika (Seega) Thiel. arrived in Switzerland, 1992.


Walter Thiel studied chemistry at the University of Marburg (West Germany) from 1966 to 1971, where he subsequently obtained his doctorate with A. Schweig in 1973.


He is the president of the World Association of Theoretical and Computational Chemists (WATOC) from 2011. After a post-doctoral stint at the University of Texas at Austin with M. J. S. Dewar (1973–1975), he obtained his habilitation from the University of Marburg in 1981. He was appointed Professor of Theoretical Chemistry at the University of Wuppertal (West Germany) in 1983 and Professor of Chemistry at the University of Zurich (Switzerland) in 1992.

In 1987 he was a visiting professor at the University of California at Berkeley. Since 1999, he is a director at the Max Planck Institute for Coal in Mülheim an der Ruhr (Germany) and an honorary professor at the neighboring University of Düsseldorf (Germany) since 2001. 1975 Liebig Fellowship of the Fonds der Chemischen Industrie Walter Thiel's research interests include the broad areas of theoretical chemistry, in particular quantum chemistry, and computational chemistry, with a focus on large molecules, spectroscopy, and catalysis.

His group has been involved in the development of new theoretical methods, in particular for the treatment of large molecules, and applies theoretical calculations to concrete chemical problems, usually in close collaboration with experimentalists. Selected methodological contributions Development and implementation of semi-empirical quantum-chemical methods: Development of MNDO-type approaches (orthogonalization-corrected OMx methods, MNDO/d for transition metals). Computation of NMR-chemical shifts.

Semi-empirical multireference configuration interaction (MRCI) methods. Semi-empirical method developments are implemented in the MNDO program. Development of combined quantum mechanics/molecular mechanics (QM/MM) methods: Coupling approaches, boundary method, QM/MM structure optimization.

Developments in this area are implemented within the ChemShell package. Selected application areas Highly accurate correlated QM calculations for smaller molecules. Theoretical rovibrational spectroscopy.

Transition-metal chemistry, homogeneous catalysis (typically applying density-functional theory methods). Mechanisms of enzymatic reactions (using QM/MM methods).
