摘要：
Functional group substitutions (chemical mutations) in a molecular zipper complex have been used to construct a thermodynamic cycle for estimating the strength of a pi-facial H-bond between an NH group and an aromatic 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.
