Figure 4

(a) The bulk water self-diffusion coefficient DS as a function of the pressure in the range 1 bar< P < 10 kbar at different temperatures from the supercooled region 252 K to 400 K. (b) The self-Diffusion coefficient DS, at several different pressures from 1 bar to 10 kbar in an Arrhenius fit (log DS vs 1000/T). The red line represents the T* temperature crossover that identifies two different scenarios, Arrhenius for T > T* and super-Arrhenius for T < T*. I.e. the transition of water from a simple to a strong interacting structured liquid.
