查询词典 hexagonal system

Geometries of two-dimentional hexagonal net and one-dimentional chain of C36 polymers were optemized by using PM3 and B3LYP/6-31G method. Their electronic structure and stability were also discussed . Band structure were calculated at ab initio level . Compered to the solo C36 molecular ,the results indicated that C36 unit"s structure in the polymers changed obviously and the polymerization increased the system"s stabilities .
