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 is a common solvent used in NMR spectroscopy. Deuterated methanol was first detected in interstellar space was Orion-KL in 1988 by scientists at the Max Planck Institute for Radio Astronomy. [2]
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]
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 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 vast majority of molecules in a solution are solvent molecules, and most regular solvents are hydrocarbons and so contain NMR-active hydrogen-1 nuclei. In order to avoid having the signals from solvent hydrogen atoms overwhelm the experiment and interfere in analysis of the dissolved analyte, deuterated solvents are used where >99% of the ...
