Essential NMR gives scientists and engineers an easy and quick refresher on their NMR knowledge and skills. At the same time, this primer and review affords lecturers material to provide a deliver a framework of basic know-how covering all fields of NMR, i.e. NMR methodology and hardware, chemical analysis, 2D-spectroscopy, NMR imaging, flow NMR, and quality-control NMR. Concise explanatory text, with the key information, is enhanced a color illustration that graphically reinforces understanding. Rigorous derivations are avoided in favor of intuitive arguments. The book is intended for beginning graduate students and doctoral students of Physics, Chemistry, Chemical Engineering, and Material Science. No other teaching-and-learning text addresses all the different aspects of NMR in such a comprehensive and concise fashion.
