Figure 1: The distributions of hydrogen bonds related lengths and angles when glycerol concentration is 2.9M: H...O distance (A), H-O…O angle (B), O…O distance (C) and O-H…O angle (D). Note that the contributions from waterwater (ww), glycerol-water (gw), different glycerol molecules (gg) and the same glycerol molecules (ggi) have also been given for H…O distance distribution. The distributions for other glycerol concentrations are similar and have not been illustrated here.
