"Electric Polarizability" is the relative tendency of a charge distribution, like the electron cloud of an atom or molecule, to be distorted from its normal shape by an external electric field, which is applied typically by inserting the molecule in a charged parallel-plate capacitor, but may also be caused by the presence of a nearby ion or dipole.
$\alpha_{i,j} = \frac{\partial p_i}{\partial E_j}$, where $p_i$ is the cartesian component along the $i-axis$ of the electric dipole moment induced by the applied electric field strength acting on the molecule, and $E_j$ is the component along the $j-axis$ of this electric field strength.
