Bis(2,6-dimethylaryl) nitroxides showed ESR spectra of complex hyperfine structures and the coupling constants of the ring and the methyl hydrogen atoms were determined by a simulation technique.The coupling constants of the 4-ring and the 4-methyl hydrogen atoms of the aryl group, ca. 1.1 gauss, suggest a fairly great degree of conjugation between the aryl and the nitroxide group.
