Infos

This book is the perfect link for learning how to perform the experiments after only having studied theory. In eight chapters more than 50 essential NMR experiments are described in detail. Special focus is put on the organic set of NMR spectra (1H, 13C-APT, COSY, NOESY, HSQC and HMBC). Different chapters deal with advanced organic NMR, selective methods, heteronuclear NMR, relaxation and diffusion measurements, organic applications and maintenance. Every experiment has a section providing the reader with the purpose and scope of the specific experiment. Every experiment is concluded with the spectrum as it is obtained under the conditions described. Questions
and comments enable the reader to check their understanding. The authors are very experienced and the whole book is in full color, which enhances the reading experience and makes the spectra and other figures easier to understand.

This book is strongly recommended for all students and researchers who are involved in the structural elucidation of chemical compounds both in practical education and in pursuing research, in particular if they handle an NMR spectrometer.

Autor

Matthias Findeisen studied Physics at the University of Leipzig. During his Diploma course he joined 1979 the group of Prof. Artur Lösche, who established in the fifties radio frequency spectroscopy in the Physical Institute and was one of the pioneers in NMR in East Germany. This gave M.F. a little taste of NMR and, had been nosey, he stayed there for his PhD work on the field of liquid crystalline substances. Afterwards he switched to the East German Academy of Science in Leipzig and operated an NMR routine lab, which focused him to NMR in liquids and chemical analytical problems. Returning back to the Leipzig University in 1992 he kept this focus in the group of Prof. R. Borsdorf, later on conducted by Stefan Berger, than concentrating to methodological NMR subjects. Stefan Berger was intrigued by NMR after having won a bottle of beer during an introductory course in organic NMR led by Prof. H. Suhr at the University Tübingen in 1968. After a PhD thesis with Prof. Anton Rieker, in 1973 he joined Prof. J. D. Roberts at Caltec for postdoctoral work, where he also met Prof. D. M. Grant and Prof. D. Seebach, who were then guest professors in Pasadena. This period was decisive in trying for a Habilitation in NMR spectroscopy, which was achieved at the University Marburg. At the University of Leipzig he tries to combine methodological development of NMR with its application to bioorganic problems.
