摘    要:采用Gaussian03软件,用密度泛函理论的B3LYP方法在6-31G基组水平上优化了对羟基苯甲醛缩2,4-二硝基苯胺希夫碱,得到其最稳定构型及其能量。在优化结构基础上用Hartree-Fock(HF)/6-31G方法计算了该分子的红外光谱振动频率并绘制了红外光谱图,对图中各峰位进行了分析探讨。用同样的方法计算了该化合物分子的核磁共振氢谱。

关 键 词:2  4-二硝基苯胺  对羟基苯甲醛  希夫碱  Gaussian03  红外光谱  核磁共振氢谱

Abstract:The optimization of 4-(2,4-dinitrophenylimino)methyl] phenol schiff base were performed by density functional theory(DFT) method at B3LYP/6-31G level of theory with Gaussian03 software to obtain most stable configuration and energy.Based on the optimized configuration the IR vibrational frequencies and IR spectrum of this Schiff base were obtained by Hartree-Fock(HF) /6-31G method,and the peak position of the IR spectrum were analyzed.By the same method,the 1H NMR of 4-(2,4-dinitropheny-limino)methyl] phenol schiff base were obtained.
Keywords:2  4-Dinitroaniline  4-Hydroxybenzaldehyde  Schiff Base  Gaussian03  Infrared Spectra  1H NMR
