Topological properties of hydrogen bonds from MEM (filled circles) and prior (open circles) densities depending on the distance d(HO). (a) and (b) . The solid line represents the fit to the MEM values given by = 16.14 (3.76) exp[2.22 (13) d(HO)]. Dashed lines are fits to PRIOR values, with = 12.27 (68) exp[2.05 (3) d(HO)] and = 17.77 (4.35) exp[1.07 (13) d(HO)]. Dotted lines are functions derived by Espinosa, Souhassou, Lachekar & Lecomte (1999) from fits to topological properties of multipole densities, with = 8 (4) exp[2.1 (3) d(HO)] and = 330 (180) exp[2.6 (3) d(HO)].
