XPS Spectra
Sulfur (S) Compounds
The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra.
Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE.
Peak-fits are guides for practical, real-world applications. Peak-fits are not fully optimized or designed to test any theory.

| Sulfides exist with Structural Differences | |
| The oxidation state of Copper in CuS is not a formal 2+ state because Sulfur is present in various structural configurations that produce a 1:1 ratio for CuS. In contrast, the oxidation state of Copper in Cu2S is a formal 1+ state. This difference is one reason why CuS does not exhibit the expected Shake-up or Multiplet Splitting structures which appear for CuO. |
