Oliver Zerbe, Simon Jurt

Applied NMR Spectroscopy for Chemists and Life Scientists

• Broschiertes Buch

Produktbeschreibung

From complex structure elucidation to biomolecular interactions - this applicationoriented textbook covers both theory and practice of modern NMR applications.
Part one sets the stage with a general description of NMR introducing important parameters such as the chemical shift and scalar or dipolar couplings. Part two describes the theory behind NMR, providing a profound understanding of the involved spin physics, deliberately kept shorter than in other NMR textbooks, and without a rigorous mathematical treatment of all the physico-chemical computations. Part three discusses technical and practical aspects of how to use NMR. Important phenomena such as relaxation, exchange, or the nuclear Overhauser effects and the methods of modern NMR spectroscopy including multidimensional experiments, solid state NMR, and the measurement of molecular interactions are the subject of part four. The final part explains the use of NMR for the structure determination of selected classes of complex biomolecules, from steroids to peptides or proteins, nucleic acids, and carbohydrates.
For chemists as well as users of NMR technology in the biological sciences.

Autorenporträt

Oliver Zerbe is the head of the NMR department at the University of Zurich. He studied chemistry and obtained his PhD under the supervision of Wolfgang von Philipsborn in Zurich. After a postdoctoral stay in the group of Kurt Wüthrich at the ETH Zurich he conducted his habilitation with Gerd Folkers at the Institute of Pharmaceutical Sciences at the ETH. In 2003 he returned to his present location at the University of Zurich, where he is now a professor in the Department of Chemistry. His main interests are structures of proteins, particularly of membrane proteins. Oliver Zerbe is the author of approximately 100 scientific publications in peer-reviewed journals and has edited one book, "NMR in drug research". After studying chemistry at the University of Applied Sciences of Bern, Simon Jurt has been working for more than ten years in the NMR department of the University of Zurich. In addition to maintenance and trouble shooting of the NMR spectrometers, he introduces the students to the secrets of NMR spectroscopy, teaches practical NMR courses and is involved in several research projects. His main interests are the experimental NMR techniques, which allow obtaining a plethora of chemo-physical information from the spin physics.
