Abstract: UV absorption spectra of 14 derivatives of o-hydroxybenzophenone in ionized and unionized form in aqueous ethanol and in unionized form in hexane have been measured. Influence of substituents and solvents on the absorption band with the longest wavelength was discussed. The shift of this band under the influence of substituents in the unionized form was correlated with Hammett's σ constants.
