The electronic (350-900 nm), infrared and Raman (700-30 cm-1) spectra of polycrystalline samples of the mixedvalence (Ce3'/Ce4') oxysulΓde compound were investigated. The compound is a low-gap semiconductor Ce 4 O 4 S 3 with intervalence transitions in the near-infrared (ca. 850 nm) and visible (ca.
Using the previously reported vibrational results (infrared, Raman and resonance Raman spectra) for the Ce 2 O 2 S and solid compounds (see Part I), comparative lattice dynamics calculations were performed. These Ce 2.0 O 2.5 S calculations allow one to reproduce satisfactorily the experimental wave
