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 … WebDeuterated solvents are primarily used in preparing samples for solution-state nuclear magnetic resonance (NMR) to reduce the intensity of the solvent resonance. CIL offers a wide selection of deuterated solvents which would work with almost any sample type. CIL’ solvents are packaged in a variety of conveniently-sized ampoules and bottles.
