Experimental Procedures in NMR Spectroscopy,ents is given in Table 3.1. A small amount of a reference compound, usually tetramethylsilane, (CH.).Si, is added as an internal standard. For a routine continuous-wave type NMR spectrometer, about 10–20 mg of the compound is required for a good proton NMR spectrum, but in the FT instruments 1–10-mg
