Directed bonds versus diffuse bonding

Perhaps even more important than a consideration of the total cohesive energies -that is, the strength of the bond as represented by the depths of the bonding wells - is the consideration of the force constants for the stretching of the intermolecular liaisons, - that is, the flexibility of these bonds as represented by the widths of the corresponding potential energy wells. Table 12.11 is a pictorial view of the overall landscape of intermolecular bonding.
