| 摘 要： | 利用紧束缚哈密顿量计算共轭聚合物(conjugated polymers)中库仑作用对于电中性的定域激发态的影响。对于反式(CH)x计算了激子谱,重新计算了光吸收系数,对边缘部分进行了修正,所得到的结果与实验符合。

| Abstract: | The effect of the coulomb interaction on electrically neutral, localised states of conjugated polymers is investigated using a tight binding Hamiltonian. For trans- (CH)x, we calculated the excitonic spectrum, recalculated the absorption coefficient, and corrected the edge of the absorption profile. The results are shown to be in good agreement with experiments. |
