Knight Shifts

The Knight shifts of the potassium isotopes 39K and 41K were determined with high accuracy: K(39) = 0.2 7 4 35(10)% and K(41) =0.274 93(12)%. The relative isotope effect ΔK/K = -0.210 (20)% is in agreement with the hyperfine structure anomaly 39Δ41

Nuclear magnetic resonance studies of 123Sb and 121Sb in the SbxTe1-x liquid alloy system are described. Interest is focussed on the concentration dependence of the Knight shift and the NMR linewidth. Measurements of the Knight shift and linewidth have been carried out over the entire concentration range at elevated temperatures (900-1100) K. Knight shifts of 123Sb and 121Sb, measured to high precision, show hyperfine structure anomaly. Both. Knight shift and linewidth show strong dependence on the alloy concentration and extreme behavior at the concentrations 40 at.% Sb and 50 at.% Sb. respectively. The experimental results are discussed in terms of modes concerning the electronic structure of liquid semiconductors.
