During this interaction there is a net exchange of energy which leads to a change in an intrinsic property of the atomic nuclei called nuclear spin.

WebbIn 1945 two groups of physicists, one at Stanford, the other at Harvard, first reported the detection of NMR signals in condensed matter. The Harvard group led by Edward Purcell discovered the phenomenon in solid paraffin; the Stanford group, under the wing of Felix Bloch, found it in liquid water.
