orientaatiopolarisaation
Orientaatiopolarisaation refers to orientational polarization, the alignment of permanent electric dipole moments of molecules in an external electric field, producing a net polarization in the material. It is most pronounced in polar liquids and certain polymers, and is negligible in nonpolar substances.
In thermodynamic equilibrium, the degree of alignment results from balancing field-induced torque against thermal agitation. The
The orientational response is dynamic: molecular orientations relax over time, characterized by a rotational relaxation time
Implications and examples: orientational polarization contributes to the static dielectric constant Δε = εs − ε∞, and is especially important
