Induction interaction
 
Induction is one of the contributions to the Intermolecular potential.
 
Induction interaction: the electron density of a molecule distorts in response to the electric field of other molecules in its neighborhood.
 
Induction interactions (also known as polarisation).
Induction interactions are the interactions between a permanent multipole on one molecule with an induced multipole on another. When considering only dipoles you can say that a permanent dipole in one molecule can induce another dipole in another molecule. Another way to say this is: The induction of an electric moment  in one molecule due to the presence of a permanent electric moment in another molecule.  
 
When a molecule is placed in the field of other molecules, moments will be induced on that molecule due to its polarisability.  The induction interaction is the interaction of this induced moment with the field that created it.
