In this communication we discuss the applications of spin probes for characterization of diamagnetic surface active sites of oxide catalysts. The main goal of these studies is to develop spin probe techniques for determination and characterization of surface active sites that account for catalytic activity of oxide catalysts. We used donor molecules with different ionization potentials (chlorobenzene, toluene, anthracene, perylene) for characterization of electron-acceptor sites with different strengths. Acceptor molecules with different electron affinities (nitrobenzene, 1,3,5-trinitrobenzene) were used for characterization of electrondonor sites. Lewis acid sites were studied using adsorption of stable nitroxyl radicals TEMPO and TEMPONE from toluene solutions. NO is another spin probe that proved to be convenient for characterization of Lewis acid sites and Fe(II) ions. EPR silent oxygen radical anions O- on the surface of MgO and CaO were revealed using the formation of complexes with molecular oxygen, which are reliably detected by EPR
