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).
It is the sodium salt of trimethylsilylpropanesulfonic acid. A white, water-soluble solid, it is used as a chemical shift standard for proton NMR spectroscopy of aqueous solutions. [1] The chemical shift, specifically the signal for the trimethylsilyl group, is relatively insensitive to pH. [2]
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 .
SDBS includes 14700 1 H NMR spectra and 13000 13 C NMR spectra as well as FT-IR, Raman, ESR, and MS data. The data are stored and displayed as an image of the processed data. Annotation is achieved by a list of the chemical shifts correlated to letters which are also used to label a molecular line drawing.
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.

DMF can be utilized as a standard in proton NMR spectroscopy allowing for a quantitative determination of an unknown compound. In the synthesis of organometallic compounds, it is used as a source of carbon monoxide ligands. DMF is a common solvent used in electrospinning. DMF is commonly used in the solvothermal synthesis of metal–organic ...
