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. [ 2 ] 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.

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 chloroform. 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. [1]
Deuterated chloroform, also known as chloroform-d, is the organic compound with the formula CDCl 3. Deuterated chloroform is a common solvent used in NMR spectroscopy. [2] The properties of CDCl 3 and ordinary CHCl 3 are virtually identical. Deuterochloroform was first made in 1935 during the years of research on deuterium. [3]
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 .
Deuterated acetone ((CD 3) 2 CO), also known as acetone-d 6, is a form (isotopologue) of acetone (CH 3) 2 CO in which the hydrogen atom (H) is replaced with deuterium (heavy hydrogen) isotope (2 H or D). Deuterated acetone is a common solvent used in NMR spectroscopy. [1]
Deuterated dimethylformamide ((CD 3) 2 NCOD), also known as deuterated DMF, is an isotopologue of DMF ((CH 3) 2 NCOH) in which the hydrogen atom ("H") is replaced with a deuterium isotope ("D"). Deuterated DMF is a relatively uncommon solvent used in NMR spectroscopy .
