Abstract
[1-(4-acetylphenyl)-3-(2-methylphenyl)]triazene (AMT) was synthesized by experimental methods, its chemical and spectrometric properties was studied by FT-IR, FT-Raman,1H-NMR,13C-NMR and X-ray singlecrystal diffraction methods. The obtained results showed that this structure hasorthorombic system with space group of pbca and eight molecules in unit cell. Its unit cell parameters comprise a=8.0665(2), b=8.0019(2) and c=21.5249(5). Then molecular number of [1-(4-acetylphenyl)-3-(2-methylphenyl)]triazene (AMT) structure has been studied by HF/DFT methods. However, FT-IR, FT-Raman,1H-NMR, 13C-NMR spectra were analyzed that the obtained results for vibrational spectra and amount of chemical shift correspond significantly with theoretical methods. Some structural parameters such as bonds length, bonds angle and dihedral angle were studied using theoretical and experimental methods. The parameters such as thermodynamical parameters, dipole moment, HOMO and LUMO energetic values, electrophilicity (ω), chemical potential(μ), chemical hardness(η) and max amount of electronic charge transfer (ΔNmax) are calculated for this compound in conclusion. The proposed methods were successfully applied to the determination of vibrational spectra, chemical shift amounts and structural parameters.
