Inelastic neutron scattering (INS) spectra of ethene and propene adsorbed on carbon at ca. 20 K have been recorded and compared with the spectra of the solid alkenes. Differences between the alkenes in the INS spectra are attributed to the propene molecule experiencing less molecular recoil. Normal coordinate analysis reveals both alkenes to be present as physisorbed, disordered layers on carbon and that the interaction with the surface is weaker than in the corresponding crystal. On the basis of neutron powder diffraction measurements, the splitting in the C–CH3 torsion mode of solid propene is assigned to correlation field effects.

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.
