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 deuteration: a deuterated compound will show a strong peak in 2 H NMR but not proton NMR.

Deuterated solvents are a group of compounds where one or more hydrogen atoms are substituted by deuterium atoms. These isotopologues of common solvents are often used in nuclear magnetic resonance spectroscopy .

13 C NMR Spectrum of DMSO-d 6. Pure deuterated DMSO shows no peaks in 1 H NMR spectroscopy and as a result is commonly used as an NMR solvent. [2] However commercially available samples are not 100% pure and a residual DMSO-d 5 1 H NMR signal is observed at 2.50ppm (quintet, J HD =1.9Hz). The 13 C chemical shift of DMSO-d 6 is 39.52ppm (septet ...
Deuterated methanol (CD 3 OD), is a form (called an isotopologue) of methanol (CH 3 OH) in which the hydrogen atoms ("H") are replaced with deuterium (heavy hydrogen) isotope ("D"). [1] Deuterated methanol is a common solvent used in NMR spectroscopy .
Occasionally, small peaks can be seen shouldering the main 1 H NMR peaks. These peaks are not the result of proton-proton coupling, but result from the coupling of 1 H atoms to an adjoining carbon-13 (13 C) atom. These small peaks are known as carbon satellites as they are small and appear around the main 1 H peak i.e. satellite (around) to
