Nuclear Magnetic Resonance (NMR) Definition:

A form of spectroscopy that involves the study of the interaction between electromagnetic
radiation and the nuclei of atoms.

Nuclear Magnetic Resonance (NMR) Explained:

Spectroscopy experiment involves using energy in the form of electromagnetic radiation to pump the excess alpha oriented nuclei into the beta state. When the energy is removed, the energized nuclei relax back to alpha state. NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a research technique that exploits the magnetic properties of certain atomic nuclei. Thus, in organic chemistry practice, NMR analysis is used to confirm the identity of a substance.
