Chemical experience is gained from the study of real existing molecules, which are thought to be composed of distinct particles of matter, namely atomic nuclei and electrons. Abstracting the molecular structure as far as possible one arrives at molecular topology. In the course of abstraction one and the same molecular topology may be obtained from very different molecules (see Fig. 2.1). Thus the pronounced differences in the chemical properties should be an exclusive consequence of the properties of the atoms used in the various realizations of a given topology. In view of this, one may wonder whether topology plays any role at all. The successful application of topological indices in various correlations (see Chap. 11) may be evaluated as some positive evidence, but not as a rigorously proved answer: neither the physical meaning of the topological indices nor the physical interrelations causing the correlations are sufficiently understood. Contrary to that, the topological effect on molecular orbitais (TEMO)  provides solid evidence that topology determines at least a frame within which series of physically and chemically diverse species may be realized.
