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 .
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 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]
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.
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.
