This is the starting page for the NMR section. Nuclear Magnetic Resonance (NMR) is an instrumental technique that looks at atoms. Why it works is the subject of much conjecture and several theories have successfully attempted to explain it, but no single theory describes everything about the process. The fact is however, if you take a certain isotope of a certain atom and place it in a strong magnetic field, then pulse it with energy, the isotope will 'absorb' some of the energy and re-emit it so that it can be detected.
