Figure 22.4.5.4

Pairwise comparison of intermolecular-interaction density maps from the CSD and the PDB. Plots of residual density $[|\rho \hbox{(CSD)} - \rho\hbox{(PDB)}|]$ versus plot density, i.e. the average density in the least dense situation (CSD or PDB), for situations where the protonation state of the central group is (a) unambiguous, and (b) ambiguous.
