Van Der Waals Force

The Van Der Waals force is the attractive force that binds molecules to each other. These intermolecular forces were discovered in 1873 by the Dutch scientist and physicist, J. D. van der Waals.

Van der Waals published a thesis at Leiden university for his doctor's degree entitled Over de Continu´teit van den Gas- en Vloeistoftoestand .... Translation: "On the continuity of the gas and liquid state".

Van der Waals forces, which act between stable molecules, are much weaker than the forces which, for instance, we observe chemical bonding.
