Summary

''Used in concert with complementary analytical techniques such as light spectroscopy and mass spectrometry, Nuclear Magnetic Resonance (NMR) spectroscopy is the most powerful tool for the determination of organic structure. This book fosters a real-world understanding of NMR spectroscopy and how it works without burying the reader in technical details and physical and mathematical formalism.'' ''It is an ideal reference for professionals in industry and academia who use NMR spectroscopy technology, NMR facility managers, and upper-level undergraduates and graduate students in organic chemistry, biochemistry, pharmacology, biophysics, and engineering.''--BOOK JACKET.

Author Bio

Neil E. Jacobsen is the NMR Facility Manager in the Department of Chemistry at the University of Arizona in Tucson, where he also teaches graduate-level NMR courses.
