The purpose of the research reported here was to determine the structure and reactivity of adsorbed oxides of sulfur and other small sulfur-containing molecules. The molecules that were studied include the anion radicals of sulfur dioxide, sulfur trioxide, a triatomic sulfur species and carbonyl sulfide. Diamagnetic sulfate ions, as well as covalently bonded oxides of sulfur, were also studied. The adsorbent was a high surface area magnesium oxide powder. Electron paramagnetic resonance and infrared spectroscopy were used to characterize the surface species. The results show that electronegative molecules such as sulfur dioxide adsorb either by an electron transfer from the solid, forming a negative radical ion, or by reacting with the oxide ions of the lattice.
