2-(3-Phenyl-4,5-dihydro-1H-1,2,4-triazol-5-on-4-yl)-azomethine) benzoic acid molecule has been optimized using the 6-311G(d,p) basis set of DFT(B3LYP) and HF methods. Thus, the most stable geometrical conformer of the compound with different methods was obtained. 1H/ 13C-NMR chemical shifts, vibrational wavenumbers, thermodynamic parameters, molecular geometric optimizations (bond angles, bond lengths), HOMO-LUMO analyses, electronic properties, mulliken charges, dipole moment, total energy of the molecule were studied using Gaussian 09W software package. Gaussian results are drawn graphically with GaussView5.0 program. All quantum chemical computations were performed in the B3LYP functional of DFT method ve HF at the 6-311G(d,p) basis set. 1H/ 13C Nuclear magnetic Resonance spectral values were calculated in gas phase and in DMSO solvent according to GIAO method. Theoretical spectral values of the molecule were compared with experimental data obtained from the literature. In the Veda4f program, vibration types were determined and harmonic vibration frequencies were scaled with certain scale factors of different methods. In addition, thermodynamics properties (heat capacity CV0, entropy S0 and enthalpy H0), electronic properties (electronegativity (χ), electron affinity (A), global hardness (η), softness (σ), ELUMO-EHOMO energy gap (ΔEg) and ionization potential (I) were calculated. Also, the molecular surfaces such as the electron spin potential (ESP), molecular electrostatic potential (MEP), the total density, the electron density, the electrostatic potential of the molecule were visualized.
