Abstract
Functional group substitutions (chemical mutations) in a molecular zip per complex have been used to construct a thermodynamic cycle for esti mating the strength of a pi-facial H-bond between an NH group and an a romatic ring resulting in a lower limit of -4.5 +/- 0.5 kJ mol(-1) for the magnitude of the intermolecular NH-pi interaction in chloroform.
