Principles of Pulse NMR Spectroscopy
A great many, if not most, of the compounds that we encounter in our daily lives are diamagnetic. These substances are not magnetic, but if we place them in a magnetic field they will develop a net magnetization. NMR spectroscopy is concerned primarily with compounds of this type. The human body is composed primarily of diamagnetic materials and because of this whole body imaging is possible. Although whole body and other imaging experiments are dramatic and exciting new ways of applying the power and versatility of NMR methods, a wide range of other applications also exit. In this introductory chapter we outline the basic principles of NMR spectroscopy and mention a few of the more important applications (Farrar 1987).
