In this work, we will report a combined experimental and theoretical study on molecular and vibrational structure of N,N'-di(p-thiazole)formamidine (DpTF). DpTF has been synthesized and characterized by elemental analysis, FT-IR, FT-Raman, 1H NMR, 13C NMR spectroscopy and X-ray single crystal diffraction. The FT-IR and FT-Raman spectra of DpTF were recorded in the solid phase. The optimized geometry
在这项工作中,我们将报告有关N,N'-二(对噻唑)甲form(DpTF)的分子和振动结构的组合实验和理论研究。DpTF已合成,并通过元素分析,FT-IR,FT-Raman,1H NMR,13C NMR光谱和X射线单晶衍射进行了表征。在固相中记录了DpTF的FT-IR和FT-拉曼光谱。使用6-31G(d)基集,通过HF和B3LYP方法计算出优化的几何形状。DpTF的FT-IR和FT-拉曼光谱是在HF / B3LYP / 6-31G(d)级计算的,并根据势能分布(PED)分析进行了解释。标定的理论波数与实验值显示出很好的一致性。报道了对DpTF的红外光谱和拉曼光谱的详细解释。根据振动分析,计算了标题化合物在不同温度下的热力学性质,揭示了Cp,m°,Sm°,Hm°与温度之间的相关性。此外,已计算出该化合物的分子静电势图(MESP)和总偶极矩特性。
