Contraction of a dielectric in an electric-field gradient. 

Notes:

1. For example, the contraction taking place around the charged centres created as a consequence of the sudden formation of separated positive and negative charges in the process of electron transfer.
2. The thermodynamic description of electrostriction was given by Drude and Nernst in 1894 to explain the phenomenon of contraction of a continuum medium, such as an alkane, around charges suddenly produced in that medium.
