ST2 model of water

ST2 is a model for simulations of water . The ST2 model is based on the earlier Ben-Naim and Stillinger model, known as the BNS model.

Temperature of maximum density

Liquid-liquid critical point

Liu, Panagiotopoulos, and Debenedetti have located the critical point of the liquid-liquid transition to be at a temperature of $T_c=237\pm 4\mathrm{K}$, a density of ${\rho }_c=0.99\pm 0.02{\mathrm{g}/\mathrm{c}\mathrm{m}}^3$ and a pressure of $p_c=167\pm 24\mathrm{M}\mathrm{P}\mathrm{a}$.
