This can been exploited to portray and quantify entanglement in systems of weakly coupled molecular qubits, such as the (Cr7Ni)2 supramolecular dimer. The inelastic cross-section shows a fine structure associated with the qubut-qubit coupling, which allows one to directly extract the quantum concurrence in selected eigenstates .
In a recent application to the archetypal Mn12 nanomagnet , cross-section data of high quality have been used to pinpoint the eigenstates of the spin Hamiltonian. In this way, the values of exchange constants have been identified univocally.
