Abstract
In recent years, a revolution in the practice of organic chemistry has been brought about by the application of physical methods. Nuclear magnetic resonance spectroscopy has been especially important in this regard, but so many papers have been published dealing with its uses in organic chemistry that any brief review such as this one can only cover illustrative examples. After a general introduction, attention will be focussed here on several interesting structural and dynamic problems involving or related to research being carried on in our laboratories.
