This work proposes a new methodology to build interaction potentials between a highly charged metal cation and water molecules. These potentials, which can be used in classical computer simu- lations, have been fitted to reproduce quantum mechanical interaction energies (MP2 and BP86) for a wide range of [M(H2O)n]m+(H2O)l clusters (n going from...

A flexible and polarizable force field to describe acetonitrile in its three states of matter has been developed on the basis of an ab initio potential energy surface at the MP2 level. The acetonitrile molecule is represented by a sophisticated twelve-site model: the six nuclei plus six mobile charges. Three thousands structures have...

Monte Carlo simulations of liquid methanol were performed using a refined ab initio derived potential which includes polarizability, nonadditivity, and intramolecular relaxation. The results present good agreement between the energetic and structural properties predicted by the model and those predicted by ab initio calculations of methanol...

A strategy to build interaction potentials for describing ionic hydration of highly charged monoatomic cations by computer simulations, including the polarizable character of the solvent, is proposed. The method is based on the hydrated ion concept that has been previously tested for the case of Cr3+ aqueous solutions [J. Phys. Chem. 100, 11748...

Wish they all could be californium: X-ray absorption spectroscopy (black points) and Monte Carlo simulations (blue line) of Cf" in aqueous solutions have been combined to determine the ligand distance and coordination number (CN) of the Cf" aqua ion (see picture), the heaviest cation measured and simulated to date. The results confirm that a...
