The electronic spectra of carbazone in a number of organic solvents of different properties have been examined. It is deduced that in dilute solutions of basic solvents, carbazone (H2L) exists in acid-base equilibrium (H2L ⇋ HL- + H+). The proportional concentration of the base form (HL-) in a medium is largely dependent on the carbazone concentration, basicity of the organic solvent and the tendency of stabilization of the HL- form through H-bond interaction with protic solvent molecules. The observed absorption bands belonging to absorption of both H2L and HL- forms are assigned to a transition involving the whole solute associated with intramolecular CT transition. The longer wavelength band appearing in the spectra of the H2L form in the weak basic solvents (acetonitrile, acetone, dioxane and CCl4) is suggested to be due to absorption of the solvated polar complex resulting from interaction of solvent polarity with the polar solute carbonyl group
