Radial distrubution functions of oxygen and hydrogen atoms of water molecules around the atomic sites of the IP and NP solutes. In (a) and (b), the SPC (—) and TAB/10D (⋯) results for around the negative site of IP are compared under ambient conditions. In (c)–(f), only the results obtained with the SPC potential in SCW are presented.
Number of water molecules surrounding (a) an atomic site of NP and (b) a (–) site of IP: SC66 (—) and SC07 (––). The scaled number is plotted as a dotted line.
Probability distribution of the solvent electric field at the center of the solute, projected along its molecular axis: (a) NP and (b) IP. The SPC potential model was employed in the simulations.

(a) and (b) of SPC water under supercritical conditions.
Time evolution of the radial distrubution of H atoms of SPC water around the negative site of the solute subsequent to an instantaneous change in the solute charge distribution.48 The hydrogen distributions in (a), (c), and (e) describe the structural relaxation of water associated with in AW, SC66, and SC07, respectively. The corresponding distributions in the opposite case are exhibited in (b), (d), and (f). For clarity, plots of the radial distributions at later times are shifted upwards from the initial distribution according to its time evolution.
