Figure 4

(a–c) The cos θ distribution probability of the angular H–O–H bisector of the interfacial water for xH2O = 0.5 (solid lines) and 0.85 (dotted lines) for the aqueous binary mixtures of (a) ethanol, (b) methanol, and (c) formic acid. The horizontal black lines reflect a totally randomized distribution; the arrows indicate the variations of maximum (Max(PxH2O)) and minimum (Min(PxH2O)) ranges of the cos θ distribution. The percentages given in the figures indicate the relative change of these ranges, [(Max(P0.5) – Min(P0.5)) – (Max(P0.85) – Min(P0.85))]/[Max(P0.85) – Min(P0.85)].
