我们成功地获得了溶液中 poly(d A)·poly(d T)的喇曼光谱 ,并利用晶格动力学方法对于异规模型进行了简正分析。根据势能分布矩阵 (PED)对每一个模式进行了指定。结果表明异规模型的简振频率和 poly(d A)·poly(d T)的喇曼光谱符合得相当好 ,这说明溶液中的 poly(d A)· poly(d T)完全有可能保留了固体纤维中的异规模型结构。 We successfully obtained the Raman spectra of poly (d A) · poly (d T) in solution, and used the lattice dynamics method to conduct a simple analysis of the heteroscedastic model. Each mode is specified based on the potential energy distribution matrix (PED). The results show that the Raman frequency of the heteroscedastic model is in good agreement with the Raman spectrum of poly (d A) · poly (d T), which shows that poly (d A) · poly Heterogeneous model structure in solid fibers.
