摘要:
获得了2,5二甲基1,3,4噻二唑(DMETD)在乙腈、甲醇和水中的紫外吸收光谱以及三种溶剂中不同激发波长下的共振拉曼光谱,并结合含时密度泛函TDB3LYP/6-311++G(d,p)计算对DMETD的短时结构动力学进行了研究。通过固态的FTRaman、FTIR光谱和DFT计算指认了DMETD在溶剂中的共振拉曼光谱,并对DMETD共振拉曼光谱的强度模式进行了分析。结果表明DMETD在气相和溶剂中的跃迁主体都是π →π*。溶剂模型计算发现溶剂的极性对拉曼强度无影响。这样,DMETD在FranckCondon区域活性振动模大致可以指认为7个基频v8,v12,v15,v17,v22,v23和 v27以及它们的倍频和组合频,C=N和N-N伸缩振动占据了对拉曼强度的主要部分,说明S2激发态结构动力学也主要沿这两个坐标进行。
