Abstract
For 67Zn NMR lines of solutions of ZnCl2, ZnBr2, and ZnI2 in H2O and D2O an anomalous solvent isotope effect is reported. In D2O solutions the lines are shifted to higher frequencies. The difference between the shieldings in H2O and D2O is e.g. σ(H2O) - σ(D2O) = (13.1 ±0.7) ppm for a concentration of 0.02 moles zinc bromide per mole solvent.
