Radicals formed on u.v. irradiation of aqueous solutions (pH 8) of fentichlor and bithionol have been detected by e.s.r. spectroscopy. The radicals have been identified as substituted benzosemiquinone radicals and the proton hyperfine coupling constants have been assigned on the basis of methyl substitutions.
