From: Effect of temperature and illumination on pyrite oxidation between pH 2 and 6
Top panel: S 2p data for {100} pyrite, with and without uv illumination. A S 2p3/2–2p1/2 splitting of 1.18 eV and 2:1 relative peak area, along with a full width half maximum of 1.3 eV for each S 2p feature has been used to fit the data. Bottom panel: Fe 2p3/2 data for {100} pyrite with and without UV illumination. Both the S 2p and Fe 2p3/2 data suggest that UV illumination does not lead to significant changes in the pyrite structure under our experimental conditions.
