A significant structure usually produced by the UV-Vis study is that the transition of the electrons from the π(bonding) and π* (antibonding) orbitals between the ground state to excited energy states is induced by the absorption of UV and visible light [24,25]. The absorbance and ...
Considering this short state of the art, the aim of the present study is twofold. First, a supplementary long-term corrosion system is studied: the iron clamps corroded outdoors on the Metz cathedral, since the 15th centuries. Because of the potential variability of the ancient corrosion layers...
