An important role in atmospheric chemistry is that of the reactions of ozone with unsaturated organic surfaces. Potential reactions sites for the atmospheric pollutant ozone are man-made materials that contain C=C functional groups. Previous research has shown that carboxylic acid-containing products were formed when unsaturated organic monolayers on silicon react with ozone; a band at 1860cm-1 shows the formation of a strained carbonyl species; oxidation of Au - S bonds in saturated self-assembled monolayers

here could be due to the cross-linking of the terminal groups to stabilize the monolayers toward desorption from the substrate.
This article was more advanced that the article that I reviewed from the Journal of Physical Chemistry. It did not give as much detail or explanation about certain statements. Overall, the article gives evidence for the formation of inter-chain carboxylic anhydride groups from the reaction of C=C terminated alkenethiols on Au with gaseous ozone.
