Since non-enriched hydrogen is mostly protium (99.85%), with only a trace of deuterium (0.15%), this enrichment in deuterium is colloquially, though somewhat inaccurately, described as "replacement" of hydrogen ("H") with deuterium ("D").

Deuterated chloroform (CDCl 3), also known as chloroform- d, is an isotopically enriched form of chloroform (CHCl 3) in which most 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.

In carbon-13 NMR spectroscopy, the sole carbon in deuterated chloroform shows a triplet at a chemical shift of 77.16 ppm with the three peaks being about equal size, resulting from splitting by spin coupling to the attached spin-1 deuterium atom (CHCl3 has a chemical shift of 77.36 ppm).
