Some principles of NMR spectroscopy and their novel application

Nuclear magnetic resonance spectroscopy often uses complex methodologies in complex applications. In this review, some of the details of NMR spectroscopy are made more accessible and more interesting. Determinations of components of everyday interest, such as beer, peanuts, corn, and bananas, illustrate recent advances in overcoming sensitivity problems and highlight fascinating applications of relaxation methods. Examples are given of the selection of windows for the application of chemical shifts and T2 relaxation times. The innovative and unusual applications of NMR techniques demonstrate and highlight important principles of NMR spectroscopy. © 1997 John Wiley & Sons, Inc.
