Abstract In this work, the experimental and theoretical study of new semicarbazone have been reported. The new semicarbazone was synthesized and characterized by FT-IR, FT-Raman and NMR, and the crystal structure was determined by X-ray single-crystal diffraction. The crystallographic asymmetric unit was optimized using DFT method and compared with the experimental data. The experimental FT-IR and
摘要 在这项工作中,报道了新型缩氨基脲的实验和理论研究。合成了新的缩氨基脲,并通过FT-IR、FT-Raman和NMR进行了表征,并通过X射线单晶衍射确定了晶体结构。使用DFT方法优化晶体学不对称单元并与实验数据进行比较。使用 B3LYP/6-311*G(d,p) 将实验 FT-IR 和 FT-拉曼与计算的振动频率进行了比较。通过自然键轨道(NBO)分析以及分子静电势(MEP)研究稳定性和电荷离域化。1H 和 13C 化学位移值已通过 GIAO 方法计算得出。基于电子密度及其衍生物,在真实空间中进行了非共价相互作用分析,
