The purpose of these pages is to provide some explicit results from Monte Carlo simulations for TIP4P Water. It is intended to provide guides for testing codes. Reproducing these results is a test of the correctness of codes, either written by the user or obtained elsewhere. The explicit conditions for each of the sets of results are supplied so that meaningful comparisons of your results with the ones listed here are possible.
The information presented here has been organized into several different pages.
The TIP4P model of Water was developed by Jorgensen and coworkers . It models Water as a rigid molecule containing three atomic centers, one Oxygen atom and two Hydrogen atoms, and a "M-site". The Oxygen-Hydrogen bond length is fixed at 0.9572 Å and the Hydrogen-Oxygen-Hydrogen bond angle is fixed at 104.52°. The Oxygen atom has a Lennard-Jones site and a point charge while the two Hydrogen atoms have only point charges. The M-site has a point charge and is located along the interior bisector of the Hydrogen-Oxygen-Hydrogen bond angle, 0.15 Å from the Oxygen atom.
