http://muchong.com/t-2974429-1-pid-2 The Benesi–Hildebrand method is a mathematical approach used in physical chemistry for the determination of the equilibrium constant K and stoichiometry of non-bonding interactions. This method has been typically applied to reaction equilibria that form one-to-one complexes, such as charge … See more This method was first developed by Benesi and Hildebrand in 1949, as a means to explain a phenomenon where iodine changes color in various aromatic solvents. This was attributed to the formation of an … See more Although initially used in conjunction with UV/Vis spectroscopy, many modifications have been made that allow the B–H method to be … See more • Chemical equilibrium • Ultraviolet–visible spectroscopy • Job plot See more To observe one-to-one binding between a single host (H) and guest (G) using UV/Vis absorbance, the Benesi–Hildebrand method can be employed. The basis behind this method … See more In many cases, the Benesi–Hildebrand method provides excellent linear plots, and reasonable values for K and ε.
