Historical Development of NMR

This brief historical introduction is intended to give a simplified overview of some of the critical milestones of NMR mainly in chemical applications, excluding the innovations in the held of proteins, solid state, and magnetic resonance in clinical medicine. To hnd out more details, see the articles written by Emsley and Feeney [23], Shoolery [24], and Freeman [25], and their included references.

It is possible to obtain NMR spectra of nearly all elements, although not always from observing the isotope with the highest natural abundance, as can be seen from the examples of carbon and oxygen. For reasons connected with the historical development of NMR spectroscopy, nuclei of all species other than H are referred to as heteronuclei.
