What is NMR Nuclear Magnetic Resonance (NMR) Spectroscopy involves the absorption of radio frequency radiation by atomic nuclei in anapplied magnetic field. Any atomic nucleus which possesses either odd mass, odd atomic number, or both has spin angular momentum and a magnetic moment.

Nuclear Spin The nuclear spin quantum number, I, determines the allowed spin states for a nucleus: allowed spin states = 2I + 1 For hydrogen (I=), there are two spin states (2() + 1 = 2) for its nucleus: clockwise (+) or counterclockwise (-) spin. In the absence of an external magnetic field, these magnetic moments are randomly oriented in all directions. If an external magnetic field is applied, the nuclear spins of the hydrogen nuclei orient themselves either in alignment with or in opposition to the field.
