Rotational tunneling of methane on MgO surfaces: A neutron scattering study

High‐resolution inelastic neutron scattering was used to investigate the rotational tunneling of methane molecules in a ■×■R45° commensurate, square‐lattice–solid monolayer adsorbed on MgO (100) surfaces. Good matches to the observed transition energies were obtained using potential functions with C2v symmetry, suggesting that the preferred orientation of the molecule is the dipod‐down configuration with two opposite edges of the H‐atom tetrahedron parallel to the surface plane.
