The Ce 3<I>d</I> and 4<I>d</I> core X-ray photoemission spectra (3<I>d</I> and 4<I>d</I> XPS) of Ce compounds are studied based on the impurity Anderson model considering atomic multiplets arising from electron-electron interaction. We make a consistent analysis of 3<I>d</I> and 4<I>d</I> XPS of trivalent Ce compounds CeF<SUB>3</SUB>, CeCl<SUB>3</SUB> and Ce<SUB>2</SUB>O<SUB>3</SUB>, which can only be made by considering the atomic multiplets. We also apply the approach to the interpretation of the spectra of mixed valent Ce systems Ce–Ni compounds and CeO<SUB>2</SUB>. We show that the analysis of the multiplet structure gives information about many-body electronic states of the system.
