Synthesis of aromatic schiff base derivatives this investigation of structures by spectroscopic and theorti̇cal methods

In this study, six different Schiff base ligands were synthesized using salicylaldehyde as aldehyde and 4-bromoaniline, 4-aminophenol, 4-methoxyaniline, 4-aminoacetophenone, 2-nitroaniline, 4-aminobenzonitrile, as amine. The synthesized Schiff base derivatives were examined experimentally by Infrared, Nuclear Magnetic Resonance, Ultraviolet-Visible Spectroscopy. ChemOffice 2015, ChemAxon MarvinSketch and Gaussian 09W package programs were used for the theoretical calculations and the findings were compared with the experimental observation results.
