WebThe exchange reaction H2+D2→2HD was studied as a function of the angle of incidence (polar and azimuthal) of the beam of reactants on two stepped platinum surfaces, the Pt (S) ‐ [6 (111) × (111)] and Pt (S) ‐ [5 (111) × (111)]. The reaction probability was found to depend markedly on the direction of approach of the reactants to the step structure.
