A method is herein described for determining in situ the atomic magnetic susceptibility of a metal ion in an electrogenerated complex (corrected by the diamagnetic susceptibility associated with the ligands) in aqueous solutions by monitoring the shift in the (water) proton resonance present as an adventitious impurity in the D 2 O-based electrolyte. As predicted by Evans formalism, the total shift for mixtures of the diamagnetic [Fe(CN) 6 ] 4- and paramagnetic [Fe(CN) 6 ] 3- prepared electrochemically in situ was found to be proportional to the concentration of [Fe(CN) 6 ] 3- . Furthermore, the magnitude of the molar atomic magnetic susceptibility of the latter species derived from the in situ measurements was found to be in good agreement with values reported in the literature.
