This project is in the general area of analytical and surface                   chemistry and in the subfield of gas-surface reaction dynamics.                 The research program will investigate the forces between a                      diatomic molecule and a surface when the molecule is crossing                   an activation barrier prior to dissociative chemisorption or                    associative desorption.  The anisotropy of the reactive                         gas-surface potential will be probed as a function of molecular                 orientation geometry using multiphoton laser ionization                         spectroscopy to detect the specific states of the products of                   activated associative recombination.  Angle-selected,                           velocity-selected, polarization spectroscopy will be employed                   to detect specific chemical events.                                                                                                                             The results of these experimental studies will provide detailed                 new insights into how chemical reactions occur on surfaces.  In                 addition they will enable precise testing of theoretical                        methods of modeling the interaction of molecules with surfaces.                 Development of reliable methods for constructing potential                      energy surfaces will in turn facilitate modeling of surface                     chemical reactions.
