Abstract
Magnetic resonance techniques are very powerful for the investigation of magnetic molecular materials1–3. In fact electron paramagnetic resonance (EPR) can provide information on the nature of the ground state, and in some cases also of the excited states, on the delocalization of the spin density on the paramagnetic molecule, on the magnetic and crystal field anisotropy, on the dimensionality of the magnetic system, and on the spin dynamics at relatively high frequencies. Nuclear magnetic resonance (NMR) on the other hand can provide information on the sign and the intensity of the spin density, on the dimensionality of the spin system, and on the spin dynamics at relatively low frequencies4. Therefore, the two techniques are largely complementary to each other, and should be used whenever a detailed understanding of the magnetic materials is needed.
