Web* HOD Peaks - NMR spectra of “neat” deuterated solvent always exhibit a peak due to H 20 in addition to the residual solvent peak. When the exchange rate between H 0 and HDO is slow on the NMR timescale the water peak appears as two peaks, a singlet corresponding to H 20 and a 1:1:1 triplet corresponding to HDO.

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.
