Structural Feature of Essentially Disconnected Polyhex Graph
Shouliu Wei · Journal of Kunming University of Science and Technology · 2008
An essentially disconnected polyhex graph is defined as a benzenoid system or a coronoid system which has fixed bonds and some Kekule structures.It is proved that the subgraph,for an essentially disconnected benzenoid system or coronoid system,obtained by deleting all the fixed single bonds and all the end vertices of the fixed double bonds,has at least two normal components.In this paper,a uniform character,i.e.the above subgraph is disconnected,is given to recognize essentially disconnected polyhexe graph.
