45Sc NMR chemical shifts, linewidths, and longitudinal relaxation rates have been measured in aqueous solutions of scandium chloride and sulphate as a function of the appropriate acid. A common typical behaviour of these parameters without sudden changes has been observed. Also signals in the basic range have been obtained. H2O -D2O solvent isotope effects on Larmor frequency and relaxation rates are presented.

From measurements of the Larmor frequencies of 2H, 5~ and 51V in aqueous vanadate solution the ratio of the gl-factors of 5~ and 5~V and the nuclear magnetic moments of 5~ and S~V are derived. The ratio of the longitudinal relaxation times T 1 in VOC13 yields the ratio of the quadrupole moments ]Q(5~ In the 3d 3 4s 2 4F3/2 atomic ground state the hyperfine structure anomaly is smaller than 1-10 -5.
