In this studythree Schiff base ligands derived of 2-hydroxybenzaldehyde: H2L1, H2L2 and H2L3 have been subjected to theoretical studies by using density functional theory (DFT) calculations. The electronic properties such as highest occupied molecular orbital (HOMO), lowest unoccupied molecular orbital (LUMO) energy, HOMO-LUMO gap energy, RHF energy, some of important bond lengths and angles, dipole moment and molecular densities have been investigated. Also the calculated IR spectra of these ligands are in good consistency with the experimental results.
在这项研究中,由2hydroxybenzaldehyde衍生的3个Schiff基联结:H2L1,H2
L2和H2L3通过使用密度功能理论(DFT)计算进行了理论研究。研究了电子属性,如最高占用分子轨道(HOMO),最低无占用分子轨道(LUMO)能量,HOMO-LUMO差距能量,RHF能量,一些重要的连接长度和角度,二极时刻和分子密度。
