A force between molecules, including effects of electrostatics, polarizability and London dispersion forces. Hydrogen bonds describe a directional interaction pattern rather than an additional fundamental force to add independently to all those components.
Intermolecular forces are the forces of attraction or repulsion that occur between neighboring particles (atoms, molecules, or ions) in a substance. These forces play a crucial role in determining the physical properties of substances, such as boiling and melting points, vapor pressures, and solubility.
