Results for density, coordination number, surface tension, dielectric constant, and self-diffusion coefficient are presented in Table , and the percent difference between the calculated and experimental value is shown in Figure , Supporting Information. For the settings employed in this work, the OPC model provided the best average agreement with experimental data for these properties, while the TIP4P/ε and TIP4P-FB models were the only models with all properties within 10% of experimental values. Subdividing the data by model type, the OPC3, OPC, TIP5P, and SPC/Fw models provided the best agreement for 3-point, 4-point, 5-point, and flexible models, respectively. The only polarizable model examined in this work, SWM4-NDP, also performed reasonably well, with an average difference from experimental values of less than 10%. Although many models were not specifically parameterized or tested for all of the properties examined here, we note a general improvement in agreement with experimental values as a function of publication year. One notable exception is the SPC/E model, which despite being published in 1987 still performs quite well under the conditions employed in this work. We emphasize here that we are not claiming to have found the "best" models, but rather for the system size and simulation settings we chose for this study, these are the models that present the best agreement with the experimental values we chose to compare to. We will discuss each property in more detail in the following sections.
