The study involves the application of quantum mechanical calculations using density function theory (DFT) with B3LYP/6-31G on a number of nitrone compounds that containing substitutes (OCH3 , CH 3, NO2 , OH , Br , Cl) for the purpose of calculation the equilibrium geometries, energies of HOMO , LUMO orbital , ionization energies , electronic densities , the vibrational modes .
The effect of substitutes on stability of each studied molecule is investigated . The standard thermodynamic functions ( U0 , H0 , S0 ,G0 ,A0 ) and Ultraviolet spectra for all substituted nitrone molecules were also investigated.These compounds are compared with the nonsubstituted nitrone compound .
