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 ...

hydrogen-bonded to the solvent, and solutes have only a negligible effect on its chemical shift. This is also true Experimental Section for D2O; the chemical shift of the residual HDO is very NMR spectra were taken in a Bruker DPX-300 instrument temperature-dependent (vide infra) but, maybe...

Chemical shift is the most valuable observable in NMR spectroscopy. It is easily accessible, can be precisely measured with high reproducibility, and most importantly is exquisitely sensitive to even a subtle change in biomolecular conformations. It has been well established that chemical shifts of pro...

Also, any potential hydrogenbond acceptor will tend to shift the water signal downfield; this is particularly true for nonpolar solvents. In contrast, in e.g. DMSO the water is already strongly hydrogen-bonded to the solvent, and solutes have only a negligible effect on its chemical shift. ...
