An x-ray photoelectron spectroscopic (XPS) study of a thin film of S 2N2 at -100°C, involving the valence band, core-level and core-level shakeup, and energy-loss spectra, is reported. The results are analyzed in terms of a molecular orbital model and previous optical data. In addition, the thermally induced solid state polymerization of S 2N2 to metallic (SN)x was studied by recording the XPS spectra at -40, 0, and 20°C. The valence band data show changes of the highest filled molecular orbitale of S2N2, consistent with the process of polymerization to the metallic state.
