WebApr 22, 2000 · Deuterated dimethylsulfoxide (d 6-DMSO) is one of the most commonly used NMR solvents, in part due to its ability to dissolve compounds with poor solubility in other common NMR solvents.However, the hygroscopic nature of DMSO often leads to a substantial water signal at 3.35 ppm in the 1 H NMR spectrum which can obscure C–H … 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.
