NMR solvent

NMR or Nuclear Magnetic Resonance Spectroscopy is a technique for determining the structure of organic compounds.

A solvent is used, although some are hydrogen bonding partners, so there are different shifts of proton groups depending on the solvent. The changes are minor, only about 0.1ppm, however, spectra with benzene as a slovent shoe small shifts, while acetone as a solvent has a shift five times greater.

Common Solvents

 * Chloroform-d is the most common solvent because it has good solubilizing character and is generally unreactive.
 * Benzene-d6
 * Acetone d-6
 * Dimethyl sulfoxide d-6

Greener Alternatives

 *  Dichloromethane-d
 * Deuterium Oxide

Do you use a greener alternative as an NMR solvent? Yes, Dichloromethane-d Yes, Deuterium Oxide Yes, Other No, these don’t work as well
