Electronic Absorption Spectra of 5,7-Dibromo-8-hydroxy Quinoline

Abstract

The present paper presents the electronic absorption spectra of 5,7-dibromo-8-hydroxy quinoline. The effect of solvents viz., ethanol, methanol and water has also been studied and discussed on the electronic transitions of the said molecules. The spectra have been recorded in the region 1900- 4000 Å. The transitions have been identified as ¹A' → ¹A' under the Cs symmetry of the molecules studied, corresponding to ¹B_su → ¹A_g transition.
