XPS core level spectra of Y123 compounds doped by C, B, S, P. and Se elements are presented. It is found that the C1s, B1s, S2p, P2p, and Se3d binding energies of doped compounds are close to those of CaCO3, FeBO3, CuSO4, NaH2PO4, and SeO2 reference compounds. It is concluded that these impurity elements form oxyanion groups in Y123 compounds.
