| Abstract: | Paramagnetic complexes with charge transfer formed upon adsorption of anthraquinone on the surface of aluminium oxide were studied with EPR and ENDOR methods. A hyper-fine structure due to the interaction of unpaired electron with one and two27Al nuclei of surface Lewis acid centers was observed. The process of complex decomposition in the presence of water on the surface was studied. |
