THEORETICAL STUDY ON THE CHARACTERIZATION OF 1,3-DIBENZOYLIMIDAZOLIDINE-2-THIONE BY QUANTUM MECHANICAL METHODS
Öz
In this study, the optimized molecular structures, vibrational frequencies, corresponding vibrational assignments, thermodynamic properties, atomic charges, 1H and 13C NMR chemical shifts, and ultra violet (UV–vis) spectra of 1,3-Dibenzoylimidazolidine-2-thione molecule have been investigated using ab initio Hartree–Fock (HF) and Density Functional Theory (B3LYP) methods at 6–31G (d,p) basis set. The bond lengths and bond angles obtained have been seen to be good agreement with the experimental data. All the calculated vibrational frequencies have been compared with each other. The correlation coefficient has been determined as 0.9991. Moreover, we have not only simulated frontier molecular orbitals (FMO) and molecular electrostatic potential (MEP) but also evaluated the transition state and energy band gap clearly. Infrared intensities and Raman activities have also been reported.
