Molecular complexes. Part IV. Further investigations of the mechanism of complex formation of aliphatic with aromatic molecules

Abstract

The mechanism of complex formation between nitroform and some methyl-benzenes is interpreted in terms of local dipole-induced dipole interactions in such a manner that the electric fields associated with the polar bonds in nitroform polarise the aromatic molecules. The relationship between the equilibrium constants and the corresponding calculated interaction energies is discussed and shown, for the symmetrical methyl-benzenes, to be in good agreement with that found in a previous publication.
