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.
