%0 Journal Article %T Structural and Optical Properties of Some 5, 8-Diaminoquinoxaline Schiff Bases: Quantum Chemical Calculations %A Vahideh Hadigheh-Rezvan %J - %D 2018 %X The molecular structure and optical properties of Schiff bases derived from condensation 4-substituated benzaldehyde (1) and 5, 8-diaminoquinoxaline were researched. These Schiff bases were survived using DFT/B3LYP method and 6-311++G (d, p) basis sets. This is the first report on the linear, non-linear optical properties and HOMO-LUMO molecular orbitals analysis of these compounds. Also, some quantum chemical parameters derived from frontier molecular orbitals were studied %K Vahideh Hadigheh-Rezvan* %K Bahareh Pilevar-Maleki %K Dipole moment %K Polarizability %K Density functional theory (DFT) %K Optical properties %K Hyperpolarizability %K 5 %K 8-diaminoquinoxaline %K Frontier molecular orbitals %K Schiff bases %U https://www.imedpub.com/abstract/structural-and-optical-properties-of-some-5-8diaminoquinoxaline-schiff-bases-quantum-chemical-calculations-21748.html
