The free energy difference between 3-point water models

By Paul M. King


This paper describes precise calculations to determine the free energy differences between 3-point models of liquid water, using the method of thermodynamic integration and molecular dynamics. For the three models considered in this study the order of thermodynamic stability at 300 K and 1 atm pressure is SPC/E > SPC > TIP3P. The magnitudes of these stabilities are quantified and an estimate of the precision of the values is made
