Hydroxyl dihedral distribution.

<p>A) Distribution of dihedral angles in radians for hydroxyls adjacent to any aromatic six-membered rings in the Cambridge Structural Database<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0075992#pone.0075992-Allen2" target="_blank">[133]</a>. Inset images show a phenol with the dihedral angle marked, B) is an example of off-planar aromatic hydroxyls produced by DOCK3.5.54, DOCK3.6 or in this paper as the “No Reset” option, C) is the Reset Hydroxyl version. The bin from 3.1 to −3.1 is shown only at left.</p>
