The polarizability.
The polarizability is how easily a charge density can acquire an induced dipole from an external perturbation.
)
The perturbation would have to be from an electric field, as we expect charge-charge interaction to cause distortion of charge density.
If the electric field is aligned along the direction of the principal polarizability axis, the polarizability is given by:
vecmu = alphavecE→μ=α→E
[(mu_x),(mu_y),(mu_z)] = [(alpha_(x x), alpha_(xy), alpha_(xz)),(alpha_(xy), alpha_(yy), alpha_(yz)),(alpha_(xz), alpha_(yz), alpha_(zz))][(E_x),(E_y),(E_z)] where
vecmu is the electric dipole moment andvecE is the electric field.
