Deuterium NMR is NMR spectroscopy of deuterium, an isotope of hydrogen.
Deuterium is an isotope with spin = 1, unlike hydrogen-1, which has spin = 1/2. The term deuteron NMR, in direct analogy to proton NMR, is also used. Deuterium NMR has a range of chemical shift similar to proton NMR but with poor resolution, due to the smaller magnitude of the magnetic dipole moment of the deuteron relative to the proton. It may be used to verify the effectiveness of chemical reactions that install deuterium atoms on a structure: a deuterated compound will show a strong peak in the 2H-NMR spectrum. If the reaction involves replacement of an existing proton, the structurally analogous signal in the 1H-NMR spectrrum will be smaller.
