| nuclear magnetic resonance |
(NMR) A method which uses value of the absorption energy for the change in spin of a nucleus to characterize the local structure around the atom containing that nucleus. In the solid state, NMR is used to investigate the magnetic properties of a material.

| nuclear magnetic resonance spectroscopy |
A technique used to study the physical, chemical, and biological properties of matter; in this method, scientists subject a molecule to a strong magnet and watch what happens to the atoms that make up the molecule, which provides information about the molecule's composition.

| nuclear magnetic resonance |
The phenomenon in which atomic nuclei spin around the axis of a strong magnetic field. The spinning nuclei create oscillating magnetic fields and emit a detectable amount of electromagnetic radiation. [28]

Nuclear magnetic resonance (NMR) spectroscopy provides information on the position of specific atoms within a molecule by using the magnetic properties of nuclei. For more information see What is NMR spectroscopy? (University of Illinois Urbana-Champaign, USA) and What is NMR? (University of New South Wales, Australia)

| nuclear magnetic resonance |
a form of spectroscopy which depends on the absorption and emission of energy arising from changes in the spin states of the nucleus of an atom. [For aggregates of atoms, as in molecules, minor variations in these energy changes are caused by the local chemical environment. The energy changes used are in the radiofrequency range of the electromagnetic spectrum and depend upon the magnitude of an applied magnetic field.]
