基本説明
May be used a coursebook, or as supplementary reading for course codes CHX500 and CHX400. Focus on fundamental concepts in chemistry : bond theory delocalisation, aromaticity, mesomerism.
Description
(Text)
Die anregende Lektüre vermittelt Ihnen die wichtigsten Ansätze zur Beschreibung von Molekülen mit konjugierten Bindungen und ihren spezifischen Eigenschaften. Die vorgestellten Zusammenhänge zwischen Struktur, Spektren und Reaktivität lassen sich für viele organische Moleküle verallgemeinern.

Rolf Gleiter is Professor for Organic Chemistry at the Heidelberg University. He received his Ph.D. in 1964 in the field of Organic Chemistry at the University of Stuttgart with F. Effenberger. Postdoctoral work was carried out with P. von R. Schleyer at Princeton University (1965/66) and Roald Hoffmann at Cornell University (1966-68). From 1969-72 he did his habilitation at the University of Basel in the laboratory of E. Heilbronner. From 1973-979 he served as Full Professor at the Technical University of Darmstadt followed by a chair of Organic Chemistry at Heidelberg University since 1979. His fields of interest are Physical Organic Chemistry - photoelectron spectroscopy, applied quantum chemistry - and the chemistry of alkynes, strained hydrocarbons and metallic pi-complexes.Gebhard Haberhauer is Professor for Organic Chemistry at the University of Duisburg-Essen. He studied chemistry at the Universities of Vienna and Heidelberg. He received his Ph.D. from the University of Heidelberg under the supervision of Rolf Gleiter. He spent as postdoctoral fellow one year in the laboratory of J. Rebek, Jr, at the Scripps Research Institute in La Jolla. After working one year at the BASF in Ludwigshafen, he returned to the University of Heidelberg, where he did his habilitation (2001-05). In 2005, he was appointed Professor for Organic Chemistry at the University of Duisburg-Essen. His current research interests include chirality transfer and induction in molecular recognition and molecular devices.
