ABSTRACT
Schiff bases are aldehyde- or ketone-like compounds in which the carbonyl group is replaced by an imine or azomethine group. In this work, (E)-N-(3-bromo-4-fluorobenzylidene)-4-nitrobenzenamine have been synthesized and characterized by IR, 1H and 13C NMR spectral studies. Density functional theory (DFT) has been used to optimize geometrical parameters, atomic charges, vibrational wavenumbers and intensity of vibrational bands. The molecular properties HOMO-LUMO, NBO were calculated using B3LYP/6-311G (d, p) basis set. The polarizability and first order hyperpolariza-bility of the title Compound was calculated and interpreted.
