17O NMR spectra have been obtained for two orientations of a single crystal of D2O enriched to 22% in 17O. The spectra of only one orientation could be assigned. This assignment yields quadrupole coupling constants for 17O in ice as follows: | e2Qqzz/h | = 1.79±0.05 MHz, η=−1.01±0.04, where the z axis is the C2 axis of the D2O molecule The isotropic chemical shift is 612±37 ppm paramagnetic to liquid D2O.
