Nuclear magnetic resonance

Nuclear Magnetic Resonance (NMR) is a technique for noninvasively studying the interior of living organisms using microwave radiation absorbed in a magnetic field. It is less harmful than X-rays and is particularly effective at detecting light atoms, making it valuable for medical diagnostics.
