Infrared Spectra of Anthraquinone Derivatives. I. The Effect of Hydroxyl, Acetoxyl, Methoxyl, and Methyl Substitutions on the C=O Stretching Frequency.

Abstract

The infrared spectra of about 80 anthraquinone derivatives substituted with acetoxyl, hydroxyl, methoxyl, or methyl group, were measured in the dioxane solution and in the solid state. The effect of substituents on the free and chelated C=O stretching vibration frequencies was discussed.
