Crystalline electric field

WebThis chapter discusses the theory of crystalline field. An investigation of the experimental data reveals that the strengths of the various crystalline fields fall into three groups; (1) strong fields in which electrostatic potential (V C) is of the order of the energy of the mutual interaction among electrons—that is, 10 4 cm –l; (2) medium fields in which the Stark … WebThe electric field lines were radiating outward from it. And finally, the fourth Maxwell equation, which is nameless: which tells us that magnetic fields don’t diverge from anything, they only curl around. Or equivalently: there …
