Abstract
The NMR signals of the nuclei 55Mn and 2H have been investigated in aqueous solutions of permanganates. The concentration dependence of the NMR signals of 55Mn has been determined in potassium permanganate solutions in H2O and D2O and a large solvent isotope effect on the chemical shift of 55Mn has been established. The ratio of the Larmor frequencies of 55Mn relative to 2H has been measured with high accuracy. Using the concentration dependence, the ratio of the Larmor frequencies of 55Mn for infinite dilution relative to 2H in pure D2O is given. From this ratio a magnetic moment for 55Mn in the permanganate ion has been derived.Keywords
