Systems exhibiting both spin and orbital degrees of freedom, of which Er3+ isone, can offer mechanisms for manipulating and measuring spin states viaoptical excitations. Motivated by the possibility of observingphotoluminescence and electron paramagnetic resonance from the same specieslocated within a fullerene molecule, we initiated an EPR study of Er3+ inErSc2N@C80. Two orientations of the ErSc2N rotor within the C80 fullerene areobserved in EPR, consistent with earlier studies using photoluminescenceexcitation (PLE) spectroscopy. For some crystal field orientations, electronspin relaxation is driven by an Orbach process via the first excited electronicstate of the 4I_15/2 multiplet. We observe a change in the relative populationsof the two ErSc2N configurations upon the application of 532 nm illuminations,and are thus able to switch the majority cage symmetry. Thisphotoisomerisation, observable by both EPR and PLE, is metastable, lasting manyhours at 20 K.
