For a fixed reaction time and an initial
DMSO concentration, the initial O atom concentration, [O]0,
was varied and its consumption was measured, as well as the
formed concentration of both products. The results presented
in Figure 6 show that there is no linear dependence between
consumed O atom concentration and the concentration of
products formed. The reason for this is that the fast secondary
reactions O+ CH3 (12) and CH3 +CH3 (2) cannot be made
negligible, and they (especially reaction 12) influence significantly the yield of the products.
