Figure 1.
Quantum mechanical (QM) interaction energies as a function of distance between chlorobenzene and water or model compounds serving as hydrogen bond donors (HBDs) in perpendicular HBD90° and linear HBD180° orientations. Distances are based on the halogen to hydrogen bond donor antecedent (O, N, or S atom). Carbons are colored cyan, hydrogens white, oxygens red, sulfurs yellow, and chlorines green.
