5)/100 eV and quantum yields of 4·10−5–10−3, respectively. ESR study showed that hydrazyl radicals and HC·O and N·O2 are the main products of radiolysis and photolysis, and the latter decay upon heating of the sample to 190 K, whereas the hydrazyl radicals survive up to 423 K. Further heating results in thermodestruction of the hydrazides, and the ESR spectrum exhibits only a singlet with splitting at 1
低温 (77 K) γ- 和 UV 辐照取代的 N'-糠基二苯甲酰肼产生顺磁性粒子,辐射化学产率为 (0.05–0.5)/100 eV,量子产率为 4·10-5-10-3。ESR 研究表明,肼自由基和 HC·O 和 N·O2 是辐解和光解的主要产物,后者在样品加热至 190 K 时衰变,而肼自由基在高达 423 K 时仍能存活。进一步加热导致酰肼的热破坏,ESR 光谱仅显示单峰,在 1 mT 处分裂,这是多共轭化合物的特征。
