Deuterated chloroform nist
WebDeuterated chloroform (CDCl 3), also known as chloroform-d, is an isotopically enriched form of chloroform (CHCl 3) in which most of its hydrogen atoms consist of the heavier nuclide deuterium (heavy hydrogen) (D = 2 H) rather than the natural isotopic mixture in which protium (1 H) is predominant. Deuterated chloroform is by far the most common … WebMar 2, 2024 · Certainly, the most popular deuterated solvent used by chemists for NMR spectroscopy is deuterated chloroform, or CDCl 3.
