摘要
用密度泛函理论(DFT),在B3LYP/Lan l2DZ水平下,研究了两种水杨醛缩二胺类锰配合物分子几何构型和电子结构,依据Onsager自洽反应场(SCRF)模型考察了它们在不同溶剂中的溶剂效应。结果表明:溶剂效应对该体系的各电子组态能量顺序没有影响,考虑溶剂环境后对原子电荷的计算几乎无影响,随着溶剂极性的增强,体系的前线轨道能级差值△E增大,但其差异不大。
The electronic and geometric structures of two kinds of salicylidene diamine manganese complexes have been systemically studied, using the density functional theory(DFT) method at B3LYP/ Lanl2DZ level. Sovlent effects have been investigated, based on Onsager self-consistent reaction field (SCRF) model in different solvents. The calculation results show that solvent effects have no influence on the order of electronic configuration energy of the system, and the calculation to atomic charge has hardly any influence when considering the condition of solvent. With strengthening polarity of the solvent, the system molecule frontier orbital energy level △E enhances, but the diffence is not very obvious.
