Anisotropic Hyperfine Interaction in the Manganese(III) Hexaaqua Ion

Anisotropic Hyperfine Interaction in the Manganese(III) Hexaaqua Ion

Caught in the act: Until now, the spatial property of the hyperfine interaction between the S=2 electronic spin and the I=5/2 nuclear spin in any chemically relevant MnIII compound has escaped observation. By taking multifrequency electron paramagnetic resonance measurements (see graph) on the [Mn(O...

Zusammenfassung:Caught in the act: Until now, the spatial property of the hyperfine interaction between the S=2 electronic spin and the I=5/2 nuclear spin in any chemically relevant MnIII compound has escaped observation. By taking multifrequency electron paramagnetic resonance measurements (see graph) on the [Mn(OH2)6]3+ ion doped into Cs[Ga(OH2)6](SO4)⋅6 H2O, ground‐state spin Hamiltonian parameters have been determined at an unprecedented level of precision.
