Transition from that into the capable-of-exchange normal-quanta-situation-form is denaturation. In the same way : the intra-molecular devitalisation. From the viewpoint of mechanically thermodynamic systems, which can, if needed, be analyzed, the inner atomic and inner molecular state-systems [systems going through several possible states] would demand extremely complex -- practically not establishable -- system-state equations. Will not, with a new basic view, things become relatively more manageable?
