Nuclear magnetic resonance was first described independently by Felix Bloch and Edward Mills Purcell, in 1946, both of whom shared the Nobel Prize in physics in 1952 for their discovery.
Nuclear magnetic resonance (NMR) is a physical phenomenon based upon the quantum mechanical magnetic properties of an atom's nucleus. All nuclei that contain odd numbers of protons or neutrons have an intrinsic magnetic moment and angular momentum. The most commonly measured nuclei are hydrogen-1 (the most receptive isotope at natural abundance) and carbon-13, although nuclei from isotopes of many other elements can also be observed. NMR studies magnetic nuclei by aligning them with a very powerful external magnetic field and perturbing this alignment using an electromagnetic field. The resulting response to the external perturbing electromagnetic magnetic is the phenomenon that is exploited in nuclear magnetic resonance spectroscopy and magnetic resonance imaging.
