A phenomenon exhibited when atomic nuclei in a static magnetic field absorb energy from a radio-frequency field of certain characteristic frequencies. Nuclear magnetic resonance is a powerful analytical tool for the characterization of molecular structure, quantitative analysis, and the examination of dynamic processes. It is based on quantized spectral transitions between nuclear Zeeman levels of stable isotopes, and is unrelated to radioactivity. See also: Zeeman effect
