nuclear magnetic resonance

n. Abbr. NMR
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.

nuclear magnetic resonance

n
(General Physics) a technique for determining the magnetic moments of nuclei by subjecting a substance to high-frequency radiation and a large magnetic field. The technique is used as a method of determining structure. Abbreviation: NMR See also electron spin resonance

nu′clear magnet′ic res′onance


n.
the selective absorption of electromagnetic radiation by an atomic nucleus in the presence of a strong, static, magnetic field.
[1940–45]

nuclear magnetic resonance

The absorption of energy (as specific frequencies of radio waves) by the nuclei of atoms that are placed within a strong magnetic field. Because certain atoms absorb specific frequencies, nuclear magnetic resonance is used to analyze substances in spectroscopy and to examine soft body tissues in magnetic resonance imaging (MRI).
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.nuclear magnetic resonance - resonance of protons to radiation in a magnetic field
magnetic resonance - resonance of electrons or atoms or molecules or nuclei to radiation frequencies as a result of space quantization in a magnetic field
