Sigrid D. Peyerimhoff
Sigrid Doris Peyerimhoff (born January 12, 1937, in Rottweil) is a theoretical chemist and Emeritus Professor at the Institute of Physical and Theoretical Chemistry, University of Bonn, Germany. Education. After completing her "abitur", Peyerimhoff studied physics at the University of Gießen, completing her degree in 1961 and receiving her doctorate under supervision of Bernhard Kockel in 1963. After researching at the University of Chicago, the University of Washington, and Princeton University, she returned to Germany and gained her habilitation at the University of Gießen in 1967. She became professor for theoretical chemistry at the University of Mainz  in 1970, and at the University of Bonn in 1972. Quantum chemistry. Her contributions have been to the development of "ab initio" quantum chemical methods, in particular, multireference configuration interaction, and to their application in many fields of physics and chemistry. Particular emphasis has been given to electronically excited states, molecular spectra and photochemistry. Many studies are on atmospheric molecules and ions, their lifetimes in excited states and decomposition due to radiative and non-radiative processes, and on stability and spectra of clusters. Some of her students became well known for their contribution to quantum chemistry, including Bernd Engels, Stefan  Grimme, Bernd A. Hess, Christel Marian, Matthias Ernzerhoff and Bernd M. Nestmann. Awards and honors. During her career, she received several awards and memberships: She is also a member of the International Academy of Quantum Molecular Science Publications. She is the author of over 400 original articles in various international journals and coauthor of "Umweltstandards: Fakten und Bewertungsprobleme am Beispiel des Strahlenrisikos". Her history of computational chemistry in Germany is of particular note. She edited "Interactions in Molecules".
