Produktinformationen zu „NMR Spectroscopy Explained “
Understanding Nuclear Magnetic Resonance Spectroscopy provides a fresh, practical guide to NMR for both students and practitioners in a clearly-written, non-mathematical format. It gives the reader an intermediate level theoretical basis for understanding laboratory applications, developing concepts gradually within the context of examples and useful experiments.
Klappentext zu „NMR Spectroscopy Explained “
A STEP-BY-STEP APPROACH TO UNDERSTANDING NMR SPECTROSCOPYUsed 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. With an accessible, clear style and approach, NMR Spectroscopy Explained:
*
Introduces readers to modern NMR spectroscopy as it is applied to the analysis of organic compounds and biomolecules
*
Minimizes complicated theory and focuses on the practical aspects of NMR spectroscopy
*
Provides comprehensive coverage of how NMR spectroscopy experiments actually work and how to optimize them on the spectrometer
*
Provides examples of every experiment, with detailed interpretation of data
*
Presents essential descriptive theory in mainly nonmathematical terms
The guide starts with a basic model and expands it one step at a time, complete with experiments and examples, helping readers who are not experts in physics or physical chemistry to develop an empowering understanding of even the most complex biological NMR spectroscopy techniques. 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.
