Charge transfer in mixed-valence solids. Part I. Crystal spectra of chlorocuprates(I,II)
Abstract
The intensity of the mixed-valence absorption in a series of mixed-valence chlorocuprates has been measured as a function of the mole fraction of copper(I). The low intensity of the band agrees with its assignment as an intermolecular charge transfer from a chlorocuprate(I) anion to a chlorocuprate(II).
