I'm trying to perform NLO properties calculations with Gaussian and I need to calculate first hyperpolarizability. I faced in literature with static and dynamic ones. Can anyone explain the main difference between them? And which one is more important in such calculations? Thanks in advance!
Polarizability is the ability to induce electric dipole moments in a material,
the hyper just means it is large. Letter P in electrodynamics.
With an applied steady electric field this is time independent. with a time varying AC electric field this will be dynamic.
Dear Juan Weisz ,
Thank you for your answer!
One question remains: is dynamic hyperpolarizability necessary for NLO properties calculation?
Mr. Kulichenko,
Static polarizabilities are determined within the framework of the effect of the external electric field. Frequency dependent polarizabilities are the so-called dynamic polarizabilities.
