Orientational polarization happens even without the electric field. It takes place when there is a permanent dipole moment in the material. Materials such as hydrochloric acid (HCL) and water (H2O) have a net permanent dipole moment because the distribution of charge of these molecules is skewed. So, when an electric field is applied to these materials, the molecules rotate so that they can align in the direction of the field. This activity results in polarization. This kind of polarization is also affected by temperature. When no electric field is applied, the thermal agitation occurs in dipolar molecules, resulting in the cancellation of the net dipole moment. This is why the selection of dielectric material for electronic applications is made on the basis of their dependency on temperature.
