3. Chemical Ideas of QED

In Chap. 1, we have studied the symmetry-polarized internal self-stress tensor of electron. In Chap. 2, we have studied the antisymmetric component of the stress tensor of electron in detail. It remains a simple question: for what does the symmetric component work? The answer is first chemical idea of QED is the spindle structure of covalency predicted by the symmetric component of the stress tensor of electron. We have so long considered relativistic theory as merely a slight correction for the interpretation in chemical phenomena. However, we shall clarify that the Hamiltonian of QED, derived from the picture of “action through medium” based on the relativistic theory, gives a novel image of the chemical interaction even in the nonrelativistic limit. Actually, we shall use the primary Rigged QED theory for our purpose. As a result, conventional images of the chemical interaction based on “action at a distance” are replaced with the new images of them given by the picture of “action through medium” without exception. We shall visualize not only the spindle structure but also various basic chemical concepts in chemical reaction systems in real three-dimensional space. Shape volume discriminates the region of classical atoms and molecules. The regional chemical potential inequality principle gives the electron transferability from one region to another.
