iajs-110	Mahmood, Anwar Th.; Khudhair, Noor A.	Synthesis and Spectral Characterization of Some New Aromatic Schiff Bases Derivated from 2,4Dinitrophenylhydrazine	2017	17	.pdf	application/pdf	6775	394	69	The absorption bands at 224, 244, 241 and 242nm as shoulder in the electronic spectra of Schiff bases SB1 to SB4 respectively, represent the local excitations (π → π*) transitions of substituted phenyl rings which correspond the electronic transition (1A1g → 1B2u) at 256nm of benzene molecule Aromatic Schiff bases behave as flexi-dentate ligands and ordinarily coordinate through nitrogen atom of imine group, oxygen atom of the de-pronated phenolic group and other donor atoms [16].	cache/iajs-110.pdf	txt/iajs-110.txt
