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 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 .
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 .

Deuterium NMR is NMR spectroscopy of deuterium (2 H or D), an isotope of hydrogen. [1] 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]
Deuterated benzene is a common solvent used in NMR spectroscopy. It is widely used for taking spectra of organometallic compounds, which often react with the cheaper deuterated chloroform. [3] A slightly more exotic application of C 6 D 6 is in the synthesis of molecules containing a deuterated phenyl group.
The total area of the 1 ppm CH 2 peak will be twice that of the 2.5 ppm CH peak. The CH 2 peak will be split into a doublet by the CH peak—with one peak at 1 ppm + 3.5 Hz and one at 1 ppm − 3.5 Hz (total splitting or coupling constant is 7 Hz). In consequence the CH peak at 2.5 ppm will be split twice by each proton from the CH 2. The first ...
Deuterated dichloromethane (CD 2 Cl 2 or C 2 H 2 Cl 2) [a] is a form (isotopologue) of dichloromethane (DCM, CH 2 Cl 2) in which the hydrogen atoms (H) are deuterium (heavy hydrogen) (2 H or D). [2] Deuterated DCM is not a common solvent used in NMR spectroscopy as it is expensive compared to deuterated chloroform .
