Investigation of free radicals and cation-radicals of phenoxazine, phenothiazine, and phenothiazine derivatives by EPR and electron-nuclear resonance

Double electron-nuclear resonance and triple electron-nuclear-nuclear resonance have been used for the first time to determine the HFS constants and their relative signs in free radicals and cation-radicals of phenoxazine, phenothiazine, and phenothiazine, and phenothiazine derivatives.
