Popis:	The eigenstates of the antiferromagnetic spin cluster Fe6(tea)6 are studied by electron paramagnetic resonance spectroscopy at 9.5 and 94 GHz in order to characterize the interactions which are important for the magnetic properties of the molecule. Experimental results could be obtained for the first excited spin states withS= 1, 2, 3 and 4. This enables a very accurate and detailed analysis of the intramolecular interactions. It turns out that the magnetic properties of Fe6(tea)6 are determined by the isotropic exchange (J/kB = −31.5 K), the ligand-field interaction of the FeIII ions and the dipolar interaction. Other kinds of anisotropic interactions are of minor importance.
