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.
