Sigrid Doris Peyerimhoff (born 12 January 1937, in Rottweil) is a theoretical chemist and Emeritus Professor at the Institute of Physical and Theoretical Chemistry, University of Bonn, Germany.1988 Gottfried Wilhelm Leibniz-Prize 1994 Cross of Merit of the Federal Republic of Germany 2007 Cothenius-Medaille of the Academy of Sciences Leopoldina 2008 Grand Cross of Merit of the Federal Republic of Germany University of Chicago, University of Washington, Princeton University, University of Mainz, 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.
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.
During her career, she received several awards and memberships: She is also a member of the International Academy of Quantum Molecular Science She is the author of over 400 original articles in various international journals[5] and coauthor of Umweltstandards: Fakten und Bewertungsprobleme am Beispiel des Strahlenrisikos.
