Abstract
The ultra violet absorption spectra of chalcone derived from acetyl benzo oxazine have been recorded in various solvents in the range 200–400nm and the effects of solvents on the absorption spectra of title compound are interpreted by correlating the of absorption frequencies with Kirkwood function{ԑ, 1/ԑ and f(ԑ) = }. Absorption maxima observed in alcohol water mixtures and hexane is found to be the direct measure of the excited state stabilization energy of the Chalcone under investigation in various percentage of alcohol-water mixture.
