Introduction. Most NMR spectra are recorded for compounds dissolved in a solvent. Therefore, signals will be observed for the solvent and this must be accounted for in solving spectral problems. To avoid spectra dominated by the solvent signal, most 1 H NMR spectra are recorded in a deuterated solvent.
