Monte Carlo Simulation of the Local Ordering of Water Molecules. II. Spatial Correlations and Hydrogen Bonds

Resumo

The Monte Carlo method is used to calculate spatial distribution functions of oxygen and hydrogen atoms within a large-size water model (33666 SPC/E water molecules) under atmospheric pressure at room temperature. The work focuses on structural interpretation of local densities of water at the distances of about 3–5 Å from its molecules. The distribution of the distances between water molecules connected by chains of two or more hydrogen bonds indicates that the molecules between the first and second peaks of the radial distribution function (RDF) are mainly second and, to a lesser extent, third neighbors along the chain of bonds.
