title: Sign of excited spin state magnetic anisotropy parameters.
abstract: By using high frequency high field EPR spectroscopy we demonstrate how to extract the sign of magnetic anisotropy parameters pertinent to excited spin multiplets of antiferromagnetically coupled clusters. The method is demonstrated on a manganese(II) dimer.
