Differences between the two methods are discussed. Despite its severe limitations for 3d transition metals, a spin sum rule evaluation is nevertheless performed for the MnIII centres in the [MnIII6CrIII]3+ SMM to provide a simple means of comparing XMCD and spin-resolved electron spectroscopy results. © 2014 Elsevier B.V.
