The kinetics of oxygenated hydrocarbon radicals is a central element of hydrocarbon oxidn. at both low and high temps. Among the large variety of such radicals a few of them are accessible to isolated generation and direct time resolved detection using presently available laser techniques. Recent results obtained for the kinetics and product distributions of the reactions of CH3O2 with NO and O atoms and of CH3O with NO, O and O2 are presented and discussed in terms of multi-channel potential energy diagrams. Moreover, the direct gas phase detection of the hydroxy-cyclohexadienyl-radical and the kinetics of its reaction with NO2 is also reported.
