The Hubbard on-site correlation energy U and the transfer energy t for the electron hop between the copper dx?-+ and the overlapping p orbital of the nearest-neighbour oxygen atom are estimated based on the XPS results on these compounds. Using these parameters, it is predicted that the BIS spectra
