Abstract

The radical anion of (E)โ€azobenzene, generated from the neutral compound by reaction with potassium mirror in an ethereal solvent, has been fully characterized by its hyperfine data with the use of ESR, ENDOR and TRIPLEโ€resonance spectroscopy. Assignments of coupling constants to protons in the individual positions are based on comparison with the spectra of the radical anions of 4,4โ€ฒโ€dideuterio and 2,2โ€ฒโ€dimethyl derivatives. Effects of ^14^N hyperfine anisotropy on ESR spectra and of association with the counter ion K^+^ are briefly discussed.
