✦ Synopsis

The interaction of SO* and of SOz + O2 mixtures with Ag surfaces has been investigated using secondary ion mass spectroscopy.

The SOz/Ag system gave spectra which were largely composed of AgSO:, AgSOz and AgzS+ ions, indicative of the formation of S and SO4 species in the reaction. In the case of the (SO2 + Oz)/Ag system the initial species were similar to those in the previous reaction, the differences being that, as the reaction proceeded, AgSl and AgSO: disappeared to be replaced by AgzO+ and AgO+. These observations are discussed in the light of supporting evidence from other techniques and workers in the field.
