LIQUID AND SOLID-PHASES OF WATER - AN EXTENSIVE MOLECULAR-DYNAMICS SIMULATION WITH AN AB-INITIO POLARIZABLE POTENTIAL

Results are presented on the reliability of the ab initio, polarizable and flexible Nieser-Corongiu-Clementi potential at describing the structure and dynamics of the liquid and solid phases of water. For both structural and dynamic quantities the agreement between experimental and numerical results is good. A ''substance'' very similar to ''real water'' has indeed been created on the basis of ab initio quantum mechanical calculations. This gives confidence in the use of the simulations to examine features that are not directly measurable, but are or central importance in the understanding of water structure and dynamics.
