| 摘 要： | 本文建议以双极化子微观模型,根据多声子晶格弛豫理论解释顺式聚乙炔的喇曼谱。在准一维哈密顿量中考虑了电子与不同声子模的耦合,其耦合常数由红外及喇曼实验数据确定。理论计算结果与实验数据进行了比较和讨论。文中采用的方法可以推广到类似的系统

| Abstract: | A bipolaron microscopic model is proposed in this paper to interpret theoretically the Raman scattering data in cis-polyacetylene on the basis of lattice relaxation theory. The coupling of electron to different phonon modes is taken into account, the coupling constants being determined from the infrared and the Raman data. The theoretical results thus obtained are compared with the experimental data and discussed. The method used in this paper can be generalized to other similar systems. |
