Abstract

Electron Paramagnetic Resonance (EPR) spectroscopy provides a powerful tool to investi-gate paramagnetic species in a variety of materials. Although not very common, para-magnetic species play a major role in material degradation, as well as in chromoforic compounds of strong interest for Cultural Heritage. E.g., Fe(III), Mn(II), Cu(II) are very common paramagnetic species which can be easily detected and characterized through EPR. Many pigments, as well as CH materials, contain these species and can be analyzed through EPR. Also, degradation in organic materials, like paper or parchment, results often in radicals, which can be spotted through EPR. In this short presentation, the EPR technique is introduced in a simple way and a range of applications on Cultural Heritage items is shown.
