NMR

Meaning in chemistry, with examples

abbreviationCommon term

In chemistry, NMR means: Short for nuclear magnetic resonance: a method that places a sample in a strong magnetic field and uses radio waves to show how the hydrogen or carbon atoms in a molecule are arranged.

In Turkish: NMR, nükleer manyetik rezonans spektroskopisi

How it is used

The main structure-checking tool in organic labs. You run or take an NMR, a proton (¹H) or carbon (¹³C) NMR, dissolve the sample in a deuterated solvent such as CDCl₃, and discuss peaks, chemical shifts and integration.

Example sentences

  1. The proton NMR shows a three-proton singlet at 2.1 ppm, typical of a methyl ketone.

  2. Can you run an NMR of the crude product before we purify it?

Common collocations

  • proton NMR
  • carbon-13 NMR
  • run an NMR
  • NMR spectrum
  • NMR tube
  • spectroscopyThe study of how matter absorbs or emits light and other radiation, used to identify substances and measure their amounts. UV-Vis, IR and NMR are common types.
  • mass spectrometryAn analysis method that turns molecules into ions, separates the ions by their mass-to-charge ratio (m/z) and uses the result to find molecular mass and structure.
  • functional groupA specific group of atoms within a molecule, such as –OH or –COOH, that gives the molecule its typical reactions. Compounds with the same group react in similar ways.
  • isotopeOne of two or more forms of the same element whose atoms have the same number of protons but a different number of neutrons, such as carbon-12 and carbon-14.
