This project is in the general area of analytical and surface                   chemistry and in the subfield of surface chemical reaction                      dynamics.  The interaction of methyl free radicals with                         well-defined surfaces of iron and molydenum metal single                        crystals chemically modified by adsorption of one atomic layer                  of oxygen will be investigated.  Interactions of this radical                   species with polycrystalline iron and molybdenum oxide surfaces                 will also be studied.  Ultrahigh vacuum surface science                         techniques will be employed to characterize the solid surfaces                  prior to their exposure to the radicals and then to detect                      radical adsorption and reaction.  The resulting surface and                     gas-phase species will be identified and their yields                           quantified as a function of time and temperature.  These                        results will enable the kinetics and mechanisms of radical                      adsorption, desorption and surface chemical reactions to be                     elucidated.                                                                                                                                                     Chemical reactions that involve free radical intermediates are                  important in chemistry and the interactions of these species                    with surfaces are important in many technologies.  The methyl                   radical is one of the simplest and most reactive hydrocarbon                    radicals and is thought to be present as an intermediate in                     many hydrocarbon reactions that follow free radical reaction                    mechanisms.  The oxygenated surfaces to be studied in this                      research project will provide models for technological                          materials exposed to free radical reaction environments.
