Dear all
I want to know about the effect of center of symmetry on polarization
but in all articles that I read it, only, they were pointed out to
effects of centrosymmetric and non-centrosymmetric crystals. I want to
find a complete proof of this subject but I've never found it !!!!!

Thanks a lot in advance
