Nuclear magnetic resonance - Wikipedia
Nuclear magnetic resonance (NMR) is a physical phenomenon in which nuclei in a strong constant magnetic field are disturbed by a weak oscillating magnetic field (in the near field [1]) and respond by producing an electromagnetic signal with a frequency characteristic of the magnetic field at the nucleus.
Nuclear magnetic resonance spectroscopy - Wikipedia
Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique based on re-orientation of atomic nuclei with non-zero nuclear spins in an external magnetic field.

The NMR spectroscopy determines the physical and chemical properties of atoms or molecules. It relies on the phenomenon of nuclear magnetic resonance and provides detailed information about the structure, dynamics, reaction state, and chemical environment of molecules.
Nuclear Magnetic Resonance (NMR) is a powerful relatively non-selective analytical tool, which enables you to ascertain molecular structure including relative configuration, relative and absolute concentrations, and even intermolecular interactions. Once challenging and specialized NMR techniques have become routine. NMR is indeed
