nuclear magnetic resonance

A scientist uses nuclear magnetic resonance to analyze a sample.

Definition
  1. Noun:
    • A physical phenomenon: Nuclear magnetic resonance (NMR) is a property where atomic nuclei in a magnetic field absorb and re-emit electromagnetic radiation at a specific resonance frequency.
    • An analytical technique: NMR refers to a spectroscopy technique used in chemistry, physics, and medicine (as MRI) to determine the structure and properties of molecules by observing this resonance.
Usage Examples
  • Noun:
    • Nuclear magnetic resonance is a fundamental principle behind MRI scanners.
    • The chemist used nuclear magnetic resonance to determine the compound's structure.
    • The study of nuclear magnetic resonance has advanced our understanding of molecular dynamics.
Advanced Usage
  • "NMR spectroscopy": A common abbreviated form used to specify the analytical application of the phenomenon.
    • NMR spectroscopy is essential for organic chemistry research.
  • "To observe NMR": To detect or measure the nuclear magnetic resonance signal.
    • The researchers were able to observe NMR in the novel material.
Variants and Related Words
  • NMR (n): The standard abbreviation for nuclear magnetic resonance.
    • The NMR spectrum provided clear data.
  • Magnetic Resonance Imaging (MRI) (n): A medical imaging technology derived from NMR principles.
    • MRI, based on nuclear magnetic resonance, produces detailed images of the body.
  • Spectroscopy (n): The broader scientific field of studying the interaction between matter and electromagnetic radiation, which includes NMR.
Synonyms
  • Magnetic resonance (in specific contexts, though this often refers to the broader concept or its medical application).
  • Spin resonance (a more general term that can include electron spin resonance, ESR).
Related Phrases
  • NMR signal (n): The detectable electromagnetic radiation emitted during the NMR process.
    • The strength of the NMR signal depends on the concentration.
  • NMR spectrometer (n): The instrument used to perform NMR spectroscopy.
    • The lab recently acquired a new NMR spectrometer.
  • Chemical shift (n): A key parameter measured in NMR spectroscopy that provides information about the molecular environment of nuclei.
    • The chemical shift in the NMR spectrum identified the functional group.
