Homogeneous and Heterogeneous Reactions of /f-CsHnO, /i-CsHioOH and OOCsHioOH Radicals in Oxygen: Analytical Steady State Solution using the Laplace Transform A contribution to subproject CMD

The formation of photochemical tropospheric ozone, and other pollutants, is for the most part due to reactions in which VOCs and tropospheric NO% are involved. Those VOCs, emitted into the troposphere, originate from evergrowing road traffic, industrial use of solvents etc., and among them (> €4) species predominate. However, the corresponding chemical mechanisms are uncertain ; some questions relevant to the formation of ozone are misunderstood and therefore modelling studies remain unrealistic. The different reaction routes of w-pentoxy radicals in oxygen/nitrogen mixtures were thus investigated, in the temperature range 423-523 K under atmospheric pressure (Perrin et al, submitted)
