Growth mechanism of C28 (Td) fullerene: energetics and transition-state structures analysis

The ring-collapse mechanism which suggests reactions among the mono- to polycyclic carbon clusters has been analysed using quantum-chemical AM1 method. To have a cage structure like C28 (Td) fullerene, two different precursors are chosen and stacked with appropriate belts. All these stacking processes follow gradual and sequential paths. Various possible transition states have been located and characterized. Finally, based on deformation …
