Ab-initio Study Aiming Some Spectroscopic and Electronic Properties of 2-[(1H-benzimidazol-1-yl)- methyl]benzoic acid

Öz

In this study, our main aim to characterize the title molecule of C15H12N2O2 by using quantum chemistry computational method. We have performed ab-initio simulations to determine the quantized energy levels of molecules, ions or nuclei, which enable to obtain its structural parameters and, some spectroscopic, electronic and thermal properties. The compound is optimized by using ab-initio method based on the density functional theory (DFT)/B3LYP with 6-31G(d,p) basis set implemented in Gaussian 09W subprogram. The geometric parameters of bond length, bond angle and dihedral angle computed are in good agreement with those of available experiment. The same basis set and computational method have been utilized for the vibrational spectra of the title compound by using the optimized structure. The marking of the vibrational frequencies of the molecule have been carried out via the VEDA4 program (Vibrational Energy Distribution Analysis). The title molecule has 31 atoms and 87 fundamental vibrational modes, with the most bending vibrations. Since experimental chemical shifts are generally obtained in DMSO (Dimethyl Sulfoxide) and Acetonitrile solutions, the 1H and 13C NMR chemical shifts of the molecule in the same solutions are computed by using the Gauge-Independent Atomic Orbital (GIAO) approach applying DFT/B3LYP method with the basis set of 6-31G (d,p). Moreover, UV-Vis spectral analysis of the studied molecule have been investigated in both of the DMSO and Acetonitrile solvents. The maximum absorption peaks of compound have been evaluated by the Time Dependent Self-Consistent Field (TD-SCF)/DFT/B3LYP/6-31G(d,p) method. A single absorbance without any shoulder at 257 nm in both solvent have been observed. At last, electronic properties such as chemical hardness/softness, ionization potential, highest occupied molecular orbital (HOMO)-lowest unoccupied molecular orbital (LUMO) energy levels, electronegativity and energy bandgap have been predicted. Our results from DFT calculations not only aid in the interpretation of available experimental data, but also illuminate the spectroscopic and electronic properties of the title molecule in detail.
