Spectroscopy,sonance phenomenon can also be used to yield information on chemical structure and composition. This is the basis for NMR spectroscopy, which by definition is the study of the intensity patterns of NMR signal as a function of spectral frequency.

ity of MR to provide cross-sectional images, as well as chemical and physiological information, has attracted students from many disciplines. Because applied MR is multidisciplinary, it is generally taught in an informal setting rather than as structured course work. During my years of teach­ ing th
