The Knight shift and the spin-lattice relaxation time of 23Nain sodium-ammonia solutions have been measured over the concentration range from 0.3 to 16 (saturation limit) mol % metal (MPM) and the temperature range from -40 to 0 OC. The electronic contribution to the relaxation rate, (1/TJe, suggests the existence of two different composition regions: at lower metal concentrations (
