Abstract

The ESR spectra of p-benzosemiquinone radical anion included in cyclodextrins (CyDxs) in aqueous solutions were observed and analyzed. Remarkable differences in the line shape were found between the spectrum in α-CyDx aqueous solution and that in 95% ethanol. They are explained in terms of the suppressed molecular rotation of the radical included in the α-CyDx cavity. The ESR spectra of the radicals included in β- and γ-CyDx in aqueous solutions are identical with that in 95% ethanol, hence in the β- and γ-CyDx cavities the radical rotates as freely as in 95% ethanol.
