DENSITY FUNCTIONAL THEORY STUDY ON IMIDAZOLINONE DERIVATIVES
AbstractTheoretical studies on two previously synthesized 3-((2, 4-dinitrophenyl) amino)-5-methyl-2-phenylimidazolidin-4- one (1) and 3-((2,4-dinitrophenyl) amino)-2-phenylimidazolidin-4- one (2) were carried out using the Density Functional Theory method. The geometrical parameters of the molecules in the ground state was optimized at the DFT-B3LYP level of theory and ab initio method using 6-31G (d,p) basis set. Bond angle and bond length were calculated from optimized geometry. The calculated bond angle and bond length indicated that both the molecules are planar. Various quantum chemical parameters such as dipole moment (μ), energy difference (ΔE), softness (S) and global hardness (η), highest occupied molecular orbital (EHOMO) and lowest occupied molecular orbital (ELUMO) has been calculated in order to elucidate the adsorption and corrosion inhibition behavior of the molecules. The anticorrosive ability of the molecules was also established.
