It is pointed out that nuclear magnetic resonance (NMR) spectra of the naturally abundant nuchde 14N in an oriented crystal yield the nuclear magnetic shielding tensor, in addition to the nuclear electric quadrupole interaction tensor. The primary shielding anisotropy (do=) of "N in KNO, is 149.8 x

It is shown that accurate estimates of the true nuclenr magnetic shieIding constsnts in atoms czn be obtained with considerable ease from spproximate Hartree-Fock values. Extension of this estimation procedure to molecular systems is discussed. ## * Aided by a research grant tu The Johns Hopkins
## Abstract The differential Biot–Savart law of classical electrodynamics was applied to develop a ring current model for the magnetic shielding of the carbon nucleus in benzene. It is shown that the local effect of the π currents, induced by a magnetic field normal to the molecular plane, on the $
