Intermolecular forces long-range

In the previous chapters, the diffusion equation has been used extensively to model fast chemical reaction in solution. By addition of various correction factors (such as intermolecular forces, long-range transfer, solvent structure, hydrodynamic repulsion, etc.), the agreement between experiment and theory can be improved as the model becomes more realistic. Nevertheless, the reactants have been presumed to execute Brownian motion. This is only the long-time limit of their actual behaviour.

The fundamental importance of bonding energies between bodies are traditionally divided into two broad classes chemical bond (short-range force), and physical or intermolecular bond (long-range force). The energies are largely dependent on the distance at which one body feels the presence of the other. Usually, they are called a Lennard-Jones potential [34] which has a minimum value at a certain distance. 

Intermolecular and long-range forces—van der Waals forces, electrostatic forces. 

Generally speaking, intermolecular forces act over a short range. Were this not the case, the specific energy of a portion of matter would depend on its size quantities such as molar enthalpies of formation would be extensive variables On the other hand, the cumulative effects of these forces between macroscopic bodies extend over a rather long range and the discussion of such situations constitutes the chief subject of this chapter.

Liquid-solid interactions due to long-range intermolecular forces are much larger than are gas-solid interactions. This means that it is easier to collect fine particles at a liquid-liquid interface than at a gas-liquid interface. 

It is convenient, although artificial to divide intermolecular forces into two types - long-range (van der Waals) forces and short-range (valence or chemical) forces. 

The field of long-range, or intermolecular interactions is an extremely interesting and extensive topic in itself. In the context of surfaces, these forces are responsible for physisorption and can play a major role in governing processes such as rotational excitation of NO due to scattering from Ag(l 11) . For the simulations discussed here, however, these interactions do not play a major role, and so discussions of this topic are deferred to a number of review articles . ...
