A field‐mapping procedure based on volume‐selective spectroscopy is described. For proton NMR the method may be used to optimize magnet shimming, on the sample under investigation, prior to spectroscopy or imaging experiments. Examples of field maps obtained on our 4.7‐T system, using phantoms and biological samples of up to 6 cm in diameter, are presented. © 1987 Academic Press, Inc.
