In the case of orientation polarization, there is no direct mechanical force that "pulls" the dipoles to a random orientation. (unlike the two cases of electronic and ionic polarization), instead, we have many statistical events, which answer in their average results to the driving forces of electric fields, my question how this type of polarization can be correlated with the phenomena of resonance or dipole resonance.
Hi Mohammed Mesrar ,
If I have understood your question, you want to know what is the relation between the dipole resonance phenomenon and a "free dipole".
In my opinion, if you have a free dipole that is exited by an electric field, the dipole respond instantly to the electric field and its orientation will follow the exciting field polarization.
Concerning the dipole resonance, it's another concept that can be explained in quantum mechanics by a simple two states system. However, in terms of classical mechanics there is another phenomena of resonance for plasmonic and dielectric particles where the notion of dipole resonance is discussed.
I suggest to you this references :
