DMSO the water is already strongly hydrogen-bonded to the solvent, and solutes have only a negligible effect on its chemical shift. This is also true for D2O; the chemical shift of the residual HDO is very temperature-dependent (vide infra) but, maybe counter- intuitively, remarkably solute ...

The solvent chemical shifts3 were obtained from the spectra containing the solutes, and the ranges of chemical shifts (2) I.e., the signal of the proton for the isotopomer with one less deuterium than the perdeuterated material, e.g., CHCl3 in CDCl3 or C6D5H in C6D6. Except for ...
