The interaction dynamics of NO with the reactive Ru(0001) surface has been investigated with the use of supersonic molecular beam techniques. Helium scattering, King and Wells sticking measurements and time-of-flight (TOF) experiments are performed. The initial sticking coefficient is remarkably high with incident energy, varying from unity at thermal energies to ∽90% for 0.25⩽Ei⩽2.4 eV and does not seem to depend on surface temperature for 400⩽Ts⩽850 K. Counter intuitively, the non-sticking ∽10% of the incident flux has only about 12% translational energy transfer in the specular scattering direction. Molecular sticking is observed at low surface temperatures for above thermal incident energies, up to at least 0.45 eV.An attempt is made to distinguish between molecular precursor mediated pathways and direct dissociation. In order to account for the surprisingly constant initial sticking coefficients, the opening of a direct dissociative channel is proposed for beam energies exceeding the depth of the molecular chemisorption well. Several open problems are identified.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
