摘要：

Copper-thorium oxides (Cu/Th > 0.25) prepared by coprecipitation of hydroxides and calcination at 1073 K contain Cu2+ ion pairs. Since the two ions are nonequivalent the ESR parameters of the dimer spectrum change with the recording temperature. No correlation exists between the ESR spectra of the dimer and the single ion as its precursor.
