XRS spectra of CdCrxIn2−xS4 and ZnCrxAl2−xS4 spinel solid solutions are reported. A nearly constant electron density is found over all atomic sites in both series in the whole range of concentration x; this situation is related to covalency. Some interesting features in the Cr3s multiplet splitting are discussed.
