Nuclear magnetic resonance - Wikipedia

Nuclear magnetic resonance (NMR) is a physical phenomenon in which nuclei in a strong constant magnetic field are perturbed by a weak oscillating magnetic field (in the near field) and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus.This process occurs near resonance, when the oscillation frequency matches the intrinsic ...
