Reactivity of Molecular Ions

In the following sections the behavior of the molecular oxygen species is discussed with respect to exchange, oxidation, and photo-induced reactivity. 

Isotope-exchange reactions of oxygen on oxides have been reviewed by Novakova (387) and this section is restricted to those papers containing spectroscopic information about the adsorbed oxygen species. In general, there is very little direct evidence in the literature on the type of surface complexes involved in the exchange. 

The l60, 80 exchange reactions on an oxide surface can occur via several different processes (388) which may occur simultaneously  

Very little is known about the surface oxygen species which may be involved in processes (1) and (2), but process (3) can occur via a known adsorbed oxygen species in some systems. 

For place exchange, no change in the relative intensity of the lines would be
