Measuring the solid state magnetic moment

(C) The existence of $Fe^{2+}$ and $NO^+$ in the nitroprusside ion $[Fe(CN)_5NO]^{2-}$ can be established by measuring the magnetic moment of the solid compound. If iron were $Fe^{III}$ $(3d^5)$,the magnetic properties would differ significantly from the $Fe^{II}$ $(3d^6)$ state present in the complex. Measuring the magnetic moment allows for the determination of the oxidation state of the metal center.
