WebTo avoid spectra dominated by the solvent signal, most 1 H NMR spectra are recorded in a deuterated solvent. However, deuteration is not "100%", so signals for the residual protons are observed. In chloroform solvent (CDCl 3), this corresponds to CHCl 3, so a singlet signal is observed at 7.26 ppm. Web(yellow) relative to the blank (blue-green), the deuterated chloroform is acidic. Samples of deuterated chloroform which have become acidic can be easily neutralized using the following procedure: • Place 3-5 grams of a 5Å molecular sieves into a 50 or 100 g bottle of the solvent. • Swirl slightly and allow to stand overnight.
