Inelastic neutron scattering is used to probe the dynamical response of H2 films adsorbed on MgO(100) as a function of film thickness. Concomitant diffraction measurements and a reduced-dimensionality quantum dynamical model provide insight into the molecule-surface interaction potential. At monolayer thickness, the rotational motion is strongly influenced by the surface, so that the molecules behave like quasiplanar rotors. These findings have a direct impact on understanding how molecular hydrogen binds to the surface of materials used in catalytic and storage applications.

Biofuels
Biofuels continue to contribute to the attainment of the energyrelated goals of the United States, including increasing energy security and reducing the environmental degradation linked to transportation fuels. Demand for biofuel production will increase as new technologies are deployed and adopted by producers and consumers. The composition of feedstock for biofuel production, such as grain, will continue to grow. But when grain production has reached full capacity, alternative feedstocks will be needed to meet demand. The potential economic implications of biofuel production are wide-ranging and warrant further attention, especially in rural areas where the feedstocks originate.

We present a six-dimensional potential energy surface for the (H2)2 dimer based on coupled-cluster electronic structure calculations employing large atom-centered Gaussian basis sets and a small set of midbond functions at the dimer’s center of mass. The surface is intended to describe accurately the bound and quasibound states of the dimers (H2)2, (D2)2, and H2–D2 that correlate with H2 or D2 monomers in the rovibrational levels (v, j) =(0,0), (0,2), (1,0), and (1,2). We employ a close-coupled approach to compute the …
