The specific reaction parameter (SRP) approach to density functional theory (DFT) has enabled a chemically accurate description of reactive scattering experiments for activated H2-metal systems (H2 + Cu(111) and Cu(100)), but its application has not yet resulted in a similarly accurate description of non-activated or weakly activated H2-metal systems. In this study, the effect of the choice of ...

On the graphene moiré on Ir(111) a variety of highly perfect cluster superlattices can be grown as shown is for Ir, Pt, W, and Re. Even materials that do not form cluster superlattices upon room temperature deposition may be grown into such by low temperature deposition or the application of cluster seeding through Ir as shown for Au, AuIr, FeIr. Criteria for the suitability of a material to fo...

Low-temperature IR experiments on crystalline samples of trans-[Ru(NH3)4(NO) nicotinamide]3+ salts show a light-induced absorption band typical for MS1 NO linkage isomers upon exposure to 300-500 nm light from a Xe source. The formation of a metastable species is confirmed by DSC measurement on a sample irradiated at low temperature with 457 nm light from an Ar+ laser. The light-induced species...

Theoretical investigations are performed on mechanism and kinetics of the reaction of halogen peroxy radical ClOO with NO radical. The electronic structure information for both of the singlet and triplet potential energy surfaces (PESs) is obtained at the MP2/6-311 + G(2df) level of theory, and the single-point energies are refined by the CCSD(T)/6-311 + G(2df) level. The rate constants for var...

The method of molecular dynamics computer simulation has been used to examine the solid-fluid transition for the Gaussian core model in two dimensions. The system contained 780 particles subject to periodic boundary conditions, and confined to a single reduced density p* = 3• The virial pressure, mean potential energy, and pair correlation functions all indicate that the melting process is firs...
