Fig. 4

Hydrogen bond distances (HBA–H)) in units of Å for the total acceptor (a) and donor (b) databases vs the quantum chemically derived target values. c, e Show the same plots for only the oxygen and nitrogen acceptors, whereas d, f show the same plots for only the oxygen and nitrogen donors. The Pearson correlation coefficient (r) is given. The coloring of the points is according to point density: The lighter the color, the higher the point density
