摘要: 对新生育酚(维生素E)模型化合物(生育酚1:2,2-二甲基-4-异丙基-7-特丁基-6-色满酚),在甲苯溶剂里以过氧化二叔丁基引发产生生育酚氧自由基进行电子自旋共振(ESR)波谱测试,获得质子超精细分裂(hfs)偶合常数和giso因子值.以获得的质子超精细分裂偶合常数进行了计算机图谱模拟.

Abstract: Electron spin resonance measurement was performed for new tocopheroxyl model radical (7-t-butyl-4-isopropyl-2, 2-dimethyl-6-chromanoxyl radical)obtained from a new tocopherol model compound initiated by di-t-butyl peroxide in toluene.The proton hyperfine coupling constants and giso-value were determined.The computer simulation spectrum was made by use of these hyperfine coupling constants.

Key words: Tocopherol, Free radical, ESR, Hyperfine spitting
