Abstract

Cu 2p absorption spectra of divalent and monovalent copper minerals are presented. Divalent Cu gives a narrow, single line due to excitation into the empty 3d density of states, whereas monovalent Cu gives a broad band at higher energy due to transitions to the empty metal s and ligand states. The differences in the spectra can be used to distinguish between the two oxidation states, which has been applied to copper sulphide tetrahedrite complexes. © 1992.
