- Keesom force (permanent dipole – permanent dipole): The Keesom force is a temperature-dependent interaction between rotating permanent dipoles. This force only occurs between two polar molecules (or other molecules with permanent dipole moments). The Keesom force is very weak.

Jan 25, 2023 · Keesom force (permanent dipole – permanent dipole): The Keesom force is a temperature-dependent interaction between rotating permanent dipoles. This force only occurs between two polar molecules (or other molecules with permanent dipole moments).
Dipole–dipole interactions (or Keesom interactions) are electrostatic interactions between molecules which have permanent dipoles. This interaction is stronger than the London forces but is weaker than ion-ion interaction because only partial charges are involved.
The term includes: force between two permanent dipoles (Keesom force) force between a permanent dipole and a corresponding induced dipole (Debye force) force between two instantaneously induced dipoles (London dispersion force). It is also sometimes used loosely as a synonym for the totality of intermolecular forces.

o. When a polar molecule is in close proximity to a non-polar molecule, the polarizing electric field is generated by the fixed dipole (p1) of the polar molecule. This induces a dipole in the electron cloud of the non-polar molecule. The resulting interaction energy is called the Debye interaction energy. 2 α.
The Keesom interaction arises from a permanent dipole in another permanent dipole. The Debye interactions are defined as the attractive energy between a polar molecule and a nonpolar molecule (i.e., dipole-induced dipole interaction).
attractive or repulsive forces between molecules (or between parts of the same molecule) other than those due to covalent bonds, or the electrostatic interaction of ions with one another, with neutral molecules, or with charged molecules. The term includes: force between two permanent dipoles (Keesom force)
