Intermolecular Force - Debye (induced Dipole) Force

Debye (induced Dipole) Force

The induced dipole forces appear from the induction (also known as polarization), which is the attractive interaction between a permanent multipole on one molecule with an induced (by the former di/multi-pole) multipole on another. This interaction is called Debye force after Peter J.W. Debye.

The example of an induction-interaction between permanent dipole and induced dipole is the interaction between HCl and Ar. In this system, Ar experiences a dipole as its electrons are attracted (to the H side of HCl) or repelled (from the Cl side) by HCl. This kind of interaction can be expected between any polar molecule and non-polar/symmetrical molecule. The induction-interaction force is far weaker than dipole-dipole interaction, but stronger than the London dispersion force.

Famous quotes containing the word force:

    The difference between a photograph and even the most realistic painting—say, one of Courbet’s landscapes—is that in the latter there has been selection, emphasis and some discreet distortion. The painter’s deep instinctive feeling for mass and force has rearranged everything.
    Gerald Branan (1894–1987)
