Figure 3. Pair-distribution functions.
(a) O–O PDF of TIP4P/2005 water at 298 K separated into PDF:s between molecules with LSI value above and below a threshold of 0.05, showing extremes of LDL-like and HDL-like components, respectively, in the simulation. (b) Positions of the first (r1) and second (r2) peak maxima in the O–O PDF as a function of temperature. Inset shows the details of the second peak. (Adapted with error bars from ref. 49). (c) The O–O PDF as function of temperature (K) plotted as 4πr3(g(r)−1) to enhance features at long distance (Adapted from ref. 49). (d) The temperature dependence of the 11 Å correlation from c.
