Abstract

The NMR signals of207Pb were observed in a single crystal of Pb(NO3)2 and could be assigned to the four different Pb2+ sites by the dependence of the linewidths on the orientation. Four different nuclear magnetic shielding tensors with equal principal values but with different characteristic vectors could be determined. The symmetry of the shielding tensors is in agreement with the symmetry at the Pb2+ sites. It is shown, that intermolecular contributions can not account for the anisotropy of the nuclear magnetic shielding, which is 3‰ of the isotropic absolute magnetic shielding.
