Background: The quantum-chemical description of the interactions in water clusters is an essential basis for deriving accurate and physically sound models of the interaction potential for water to be used in molecular simulations. In particular, the

A systematic study is made of the accuracy and efficiency of a number of existing quadrature schemes for molecular Kohn–Sham Density-Functional Theory (DFT) using 408 molecules and 254 chemical reactions. Included are the fixed SG-x (x = 0–3) gri

The calculation of intermolecular dispersion energies within a time-dependent density-functional theory framework (TDDFT) is reviewed. While the commonly used route to compute dispersion energies is to employ the Casimir-Polder integral transform and

Contrary to recent reports, the σ-hole interaction energies of complexes between the carbon tetrahalides CX3I (X = F, Cl, Br, I) and halide anions Y− (Y = F, Cl, Br, I) are described very well by the simple Coulombic σ-hole concept if it is appli

The traditional "Fδ-" picture of fluorine suggests that it can only interact with electrophilic centers such as backbone-carbonyl carbon atoms or hydrogen-bond donors in proteins. We show that this view, which neglects polarization, is incomplete an

The self-assembly of molecular building blocks is a promising route to low-cost nanoelectronic devices. It would be very appealing to use computer-aided design to identify suitable molecules. However, molecular self-assembly is guided by weak interac

The recently introduced “Feynman” dispersion correction for MNDO (MNDO-F) has been extended to include the elements fluorine, chlorine, bromine and iodine and the original parameterization for hydrogen, carbon, nitrogen and oxygen improved by all

The folding equilibrium of the Wilcox torsion balance in solution has been studied using a molecular mechanics method for sampling the conformational space and semi-empirical and density-functional quantum chemistry methods for characterizing the rel
