„To ‚protect’ Iceland': Die britische Okkupation Islands im Zweiten Weltkrieg
Autor: Michael Penk
Publikováno v: NORDEUROPAforum - Zeitschrift für Kulturstudien, Vol 18, Iss 1, Pp 29-46 (2008)
During World War II Iceland was one of the few nations occupied by Western allied forces. On May the 10th 1940 British Royal Marines landed in Reykjavík to present a fait accompli to the Icelandic government, which had turned down earlier British re

Multiply bridgehead- and periphery-substituted tribenzotriquinacenes—highly versatile rigid molecular building blocks with C3v or C3 symmetry
Autor: Michael Penk, Dietmar Kuck, Ralph A. Krause, Hartmut Bögge, Andreas Schuster, Christian P Exner, Achim Müller, Jörg Tellenbröker
Publikováno v: Tetrahedron. 57:3587-3613
The chemical versatility of tribenzotriquinacenes as building blocks bearing rigid carbon frameworks with convex/concave molecular surfaces is presented. As revealed by X-ray single crystal structure analysis of the centro-methyl derivative, the trib

Enhanced Structure Elucidation
Autor: Michael Penk, Reinhard Neudert
Publikováno v: Journal of Chemical Information and Computer Sciences. 36:244-248
Conventional approaches to the structure elucidation of organic compounds are based on the use of spectroscopic data from different sources. The spectroscopist's task is to interpret the spectra an...
