Associations and Intermolecular Forces

From the large number of previously studied molecular associations which owe their existence to the action of intermolecular forces, we shall, in this section, which is merely a preliminary to the discussion of the properties of high polymers, select only two groups and discuss them in some detail. 

In both cases the application of the general viewpoints outlined above will afford a fairly deep insight into the mechanism of the formation of these molecular associations and throw light on the analogous relationships in high polymeric substances. 

This view receives strong support from the data in Table 47, for which we are indebted to Briegleb and his co-workers. They show that the energy of formation of the molecular association between trinitrobenzene and various aromatic hydrocarbons increases with the average polariza-
