corresponding radical states. Cation and neutral radicals were generated chemically and anion radicals were obtained electrochemically. By performing ENDOR and TRIPLE resonance experiments, complete sets of hyperfine coupling constants including their signs were accessible. The hyperfine data allowed (a) identification of the radical state present, (b) information to be obtained about the preferred conformational
各种同位素标记和/或取代的黄素已转化为它们相应的自由基状态。化学产生阳离子和中性自由基,电化学获得阴离子自由基。通过执行 ENDOR 和三重共振实验,可以访问完整的超精细耦合常数集,包括它们的符号。超精细数据允许(a)鉴定存在的自由基状态,(b)获得关于取代基的优选构象排列的信息和(c)关于取代基对自旋密度分布的影响得出的结论不同的激进状态。
