In proton NMR spectroscopy, deuterated solvent (enriched to >99% deuterium) is typically used to avoid recording a large interfering signal or signals from the proton(s) (i.e., hydrogen-1) present in the solvent itself. If nondeuterated chloroform (containing a full equivalent of protium) were used as solvent, the solvent signal would almost certainly overwhelm and obscure any nearby analyte signals. In addition, modern instruments usually require the presence of deuterated solvent, as t… WebCHCl3: InChI: InChI=1S/CHCl3/c2-1(3)4/h1H: InChIKey: HEDRZPFGACZZDS-UHFFFAOYSA-N: Molecular Weight: 119.38: Solvent: Chloroform-d; Reference=TMS …
