Keeson Interaction
The Keeson interaction is a type of intermolecular force that arises from the electrostatic attraction between permanent dipoles in polar molecules. This force is named after Willem Hendrik Keeson. The energy of a Keeson interaction depends on the inverse sixth power of the distance between the molecules. In contrast, the interaction energy of two spatially fixed dipoles depends on the inverse third power of the distance.
Key Features of the Keeson Interaction
Some of the key features of keeson interaction are:
- Permanent Dipoles: The interaction occurs only among molecules with permanent dipole moments, i.e., two polar molecules.
- Weak Interaction: Keeson interactions are very weak van der Waals interactions and do not occur in aqueous solutions.
- Orientation Effect: The electrostatic interactions align the permanent dipoles of the polar molecules, causing an orientation effect.
- Dipole-Dipole Interactions: The dipoles of the polar molecule induce the formation of opposite terminals in the non-polar molecules, leading to an orientation effect.
Some example of Keeson interaction are HCl, H2O, CO2, SO2, and NH3 etc

Van Der Waals Force
Van der Waals forces are intermolecular forces. They include attraction and repulsion between atoms and molecules. This force is fundamental in diverse fields which include condensed matter physics, polymer science, nanotechnology, supra-molecular chemistry, biological structure, and surface science.
In this article, we look into Van der Waals forces their types, the equation of the Van der Waals force, and their applications.
