nuclear magnetic resonancenuclear magnetic resonance
a phenomenon exhibited by various atomic nuclei when placed in a strong magnetic field, in which they absorb energy from specific, high-frequency radio waves: the measurements of the magnetic moments of these nuclei, esp. of hydrogen, are used in medical diagnostics, chemical research, etc. to study the nature and structure of matter
nuclear magnetic resonance
The absorption of electromagnetic radiation of a specific frequency by an atomic nucleus placed in a strong magnetic field, used especially to analyze tissues of the body in magnetic resonance imaging.
