PLANAR SCHLEGEL DIAGRAM ILLUSTRATIONS OF FULLERENES STRUCTURAL-CHANGES AND FULLERENES CAGE INTERACTIONS WITH METALS AND HYDROGENS

Two-dimensional planar Schlegel diagrams are used to displace fulleren es and to exhibit cage !cluster's vertices, faces and edges as well as cluster's extensions and changes such as isomerization, addition, eli mination etc. The Schlegel diagrams also show the possible pi bondings and free pi radicals to determine symmetry group structures as well a s to interact with the corresponding number of electrons in metals. Th e diagrams also show the possible addition of outside hydrogens and th eir movements.
