X-ray photoemission valence band spectra of CuGeO3, Bi2CuO4, and CuO single crystals are presented. Impurity cluster calculations, that well reproduce the correlated satellites and the low-lying binding energy states, clearly indicate a strong dependence of the Zhang-Rice singlets behaviour on the Cu-O bond ionicity.

Abstract
X-ray photoemission valence band spectra of CuGeO3, Bi2CuO4, and CuO single crystals are presented. Impurity cluster calculations, that well reproduce the correlated satellites and the low-lying binding energy states, clearly indicate a strong dependence of the Zhang-Rice singlets behaviour on the Cu-O bond ionicity.File in questo prodotto:
