Argus: A New Frontiers Mission Proposal To Observe Io, Ryan C. Fortenberry
Argus: A New Frontiers Mission Proposal To Observe Io, Ryan C. Fortenberry
Ryan C. Fortenberry
The Argus mission will obtain breakthrough level science advances by investigating Jupiter's innermost Galilean moon Io as outlined in the 2008 National Academies Report on choices for the next New Frontiers Announcement of Opportunity. Io has the greatest amount of volcanic activity of any planetary body in the solar system and provides a great location for studying this fundamental planetary process. The surface of Io is rich in sulfur and sulfur dioxide frost however is not as icy as other moons of the outer planets. The orbit of Io has a 2:1 orbital resonance with Jupiter's next Galilean moon Europa …

The copper(II) atoms in the two independent molecules of the title compound, [Cu(C(6)H(5)O(3))Cl(C(12)H(8)N(2))], both adopt square-pyramidal geometries. The two coordinating atoms of the two heterocyclic ligands comprise the square plane, and the chlorine atom occupies the apical position of the coordination environment.

In the centrosymmetric tetra-nuclear title compound, [Sn4(C4H9)8(C7H5O3) 4O2], one of the two independent Sn atoms is five-coordinate in a cis-C2SnO3 trigonal-bipyramidal geometry [C - Sn - C = 142.7 (1)°]; the geometry is distorted owing to a long Sn⋯O(double bond) inter-action [Sn⋯O = 2.862 (1) Å]. The other Sn atom has a bent R 2Sn skeleton [C - Sn - C = 144.0 (1)°], but the geometry is best regarded as being a trans-C2SnO4 octa-hedron as the Sn-O(single bond) inter-action is shorter [Sn - O = 2.674 (1) Å].

A Six-Dimensional H2–H2 Potential Energy Surface For Bound State Spectroscopy, Robert Hinde
A Six-Dimensional H2–H2 Potential Energy Surface For Bound State Spectroscopy, Robert Hinde
Robert Hinde
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 …

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.
