Ordering in Organic Solid Solutions
In crystals and other condensed media built of molecules, we generally encounter specific problems of ordering which do not exist in crystals built of atoms or ions. If an atom or an ion behaves as a spherical body, and vector properties of the atom (say, magnetic moments) are neglected, the mixed systems built of such particles can possess only positional ordering. The vector drawn from the unit-cell origin to the center of an atom determines its position unambiguously. The description of ordering reduces to describing the positions of points of two or more different types.
