http://www.commonorganicchemistry.com/Common_Reagents/Chloroform/Chloroform.htm WebOct 4, 2024 · Now, the NMR solvent used here is actually deuterochloroform, CDCl 3. The heavy isotope of hydrogen, deuterium or 2 H, is used in this solvent. That's because we don't want the protons in the solvent to get in the way. 2 H shows up in a completely different area of the spectrum than 1 H, so it's invisible in a regular 1 H NMR spectrum.
