| Özet |
| A new hydrazone derivative compound, 4-[(Pyridine-3-carbonyl)-hydrazonomethyl]-benzoic acid, C15H11N3O, was obtained and characterized by 1H NMR, 13C NMR and UV–Vis, FT-IR and FT-Raman spectroscopy techniques. Molecular geometry, vibrational wavenumbers, frontier molecular orbital and non-linear optical (NLO) property of the title compound were calculated using ab initio Hartree-Fock (HF) and Density Functional Theory (DFT), employing B3LYP functional at 6–311++G (d,p) basis set. 1H and 13C NMR chemical shifts were calculated by using the gauge in dependent atomic orbital (GIAO) method at the HF and B3LYP methods with different basis sets. In addition, the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) were obtained from DFT LSDA methods with 6–311++G (d,p) basis set. The NLO behaviour of the title compound has been studied by determining the electric dipole moment (μ) and hyperpolarizability (β) using both B3LYP/6–311++G (d,p) and HF/6–311++G (d,p) methods. The energy gaps s(ΔEgap=ELUMO−EHOMO) of title molecule were calculated at 4.15, 2.77 and 9.81 eV with DFT-B3LYP/6–311++ G (d,p), DFT-LSDA/6–311++ G (d,p) and HF/6–311++ G (d,p) level of theory, respectively. The calculated experimentally energy gap was found as 2.827 eV. |
