WebThere are three reasons why deuterated solvents are used in NMR spectroscopy. Reason 1: To avoid swamping by the solvent signal. There is usually much more solvent than sample in an NMR tube. An ... WebNotes on NMR Solvents. I. 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.
