The van der Waals interaction and gravitational arXiv
Van der Waals Forces Between Atoms Michael Fowler 2/28/07 Introduction The perfect gas equation of state PV = NkT is manifestly incapable of describing actual gases at... Van der Waals forces are driven by induced electrical interactions between two or more atoms or molecules that are very close to each other. Van der Waals interaction is the weakest of all intermolecular attractions between molecules. However, with a lot of Van der Waals forces interacting between two objects, the interaction can be very strong.
Van der Waals Interactions Chemistry Socratic
After the development of the theory of quantum mechanics, London quantified the van der Waals statement for molecules without a dipole and so molecular attraction forces began to be known as London/van der Waals forces (7).... Van der Waals interactions are the weakest of the intermolecular forces, and arise because the random distribution of electrons in an atom or molecule is not symmetrical, leading to an instantaneous dipole. This in turn induces a dipole in adjacent atoms or molecules, and the dipoles attract one another.

The best known example of hydrogen bonds is the attraction between The best known example of hydrogen bonds is the attraction between hydrogen and oxygen among molecules of water.

Van der Waals forces may arise from three sources. First, the molecules of some materials, although electrically neutral, may be permanent electric dipoles . Because of fixed distortion in the distribution of electric charge in the very structure of some molecules, one side of a molecule is always somewhat positive and the opposite side somewhat negative.

- The van der Waals force between two spheres of constant radii (R 1 and R 2 are treated as parameters) is then a function of separation since the force on an object is the negative of the derivative of the potential energy function, = − (). This yields:
