Knight Shift Measurements forBa135,Ba137,Cd111, andCd113

Abstract

The shift of the nuclear magnetic resonance frequency caused by the paramagnetism of the conduction electrons has been measured using a nuclear induction spectrometer. The values of the relative isotropic shift are (0.403±0.002)% for barium and (0.415±0.004)% for cadmium. The latter absorption is markedly anisotropic, the shifts perpendicular and parallel to the $c$ axis being (0.401±0.004)% and (0.444±0.004)%, respectively.
