Definition
  1. Noun:
    • Nuclear Magnetic Resonance: A physical phenomenon in which atomic nuclei in a magnetic field absorb and re-emit electromagnetic radiation at a specific resonance frequency. This property is used in spectroscopy to study the structure of molecules.
Usage Examples
  • Noun:
    • The chemist used NMR to determine the structure of the unknown compound.
    • NMR spectroscopy is a powerful analytical tool in organic chemistry.
Advanced Usage

  • "NMR spectrum": The graphical output or data obtained from an NMR experiment, showing resonance peaks.

    • The NMR spectrum revealed two distinct hydrogen environments in the molecule.

  • "NMR signal": The specific absorption or emission of radiation detected during an NMR experiment.

    • The intensity of the NMR signal corresponds to the number of equivalent nuclei.
Variants and Related Words
  • MRI (Magnetic Resonance Imaging): A medical imaging technique derived from NMR principles, used to visualize internal body structures.
    • The doctor ordered an MRI to examine the patient's knee.
Synonyms
  • Nuclear Magnetic Resonance Spectroscopy: The full technical term for the analytical technique.
  • Magnetic Resonance (MR): A broader term sometimes used interchangeably, especially in medical contexts (e.g., MR imaging).
Related Phrases

  • "run an NMR": To perform an NMR spectroscopic analysis.

    • We need to run an NMR on this sample to confirm its purity.

  • "NMR-active nucleus": A nucleus with a property (spin) that allows it to be detected by NMR.

    • Carbon-13 is an NMR-active isotope of carbon.
Noun
  1. resonance of protons to radiation in a magnetic field
