The radical anion of (E)-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 TRIPLE-resonance spectroscopy. Assignments of coupling constants to protons in the individual positions are based on comparison with the spectra of the radical anions of 4,4′-dideuterio and 2,2′-dimethyl derivatives. Effects of 14N hyperfine anisotropy on ESR spectra and of association with the counter ion K+ are briefly discussed.
(E)-偶氮苯的自由基阴离子是由中性化合物在醚溶剂中与钾镜反应生成的,已使用 ESR、ENDOR 和三重共振光谱对其超精细数据进行了充分表征。各个位置的质子的耦合常数的指定是基于与 4,4'-二氘代和 2,2'-二甲基衍生物的自由基阴离子的光谱的比较。简要讨论了 14N 超精细各向异性对 ESR 光谱的影响以及与抗衡离子 K+ 的关联。
