用EPR方法测定了三氟甲基叔丁基氮氧自由基在16种溶剂中的顺磁参数αn和α_F~β值.并对αn值与溶剂的极性参数E_T、z进行了线性相关分析,讨论了这类低位阻含氟自旋探针对研究溶剂化和探针本身结构的作用.
The paramagnetic parameters αn and α_F ~ β of trifluoromethyl tert-butyl nitroxide in 16 solvents were determined by EPR method, and linear correlation analysis between αn values and polar parameters E_T, z , Discusses the effect of such low-resistance fluorine-containing spin probes on the study of solvation and the structure of the probe itself.
