Affinity capillary electrophoresis (ACE) and quantum mechanical density functional theory (DFT) have been employed for investigation of non-covalent interactions between macrocyclic ligand, benzo-18-crown-6-ether (B18C6), and ammonium cation, NH4+. The apparent binding constant (Kb) of the B18C6-NH4+ complex in a mixed binary hydro-organic solvent system, methanol-water (50/50, v/v), was determined by ACE, whereas the structural characteristics of B18C6-NH4+ complex were calculated and described by DFT.
