The results suggested that polys had smaller band gap relative to the their homopolymers, due to the coexistence of aromatic and quinoid form and the lower LUMO energy levels.

结果显示相对於其单聚合高分子，异芳香环次甲基共轭高分子有较小的能隙是因为aromatic 和 quinoid 型态能够在共轭鍊上共存，或者是因为拥有较低的LUMO能阶所导致。

In this dissertation, a theorem to describe the relationship between the quotient group Aut/H and the set F_f is presented. And a way to find the elements of F_f that are conjugate to f is proposed. Then we prove that the quotient group Aut/H is isomorphic to S_3, the symmetric group of order 3, and H is a semidirect product group of GL_(m/2)(4) with the classical binary simplex code S_m in the linear case.
