超氧自由基。**图表**。自旋陷阱的自旋加合物5，5-二甲基-1-吡咯啉-1-氧化物在水溶液中相对不稳定。在pH 6时，电子自旋共振信号的半衰期约为80 S，而在pH 8时，半衰期仅为35 S。这些观察结果以及可能的反应产物。在计划或解释自旋俘获实验的数据时，必须考虑到在实验的时间过程中可能会出现这种情况。
The superoxide radical .**GRAPHIC**. spin adduct of the spin trap 5,5-dimethyl-1-pyrroline-1-oxide was found to be relatively unstable in aqueous solution. The half-life of the ESR signal is approximately 80 s at pH 6 and only about 35 s at pH 8. These observations as well as the possible reaction products of .**GRAPHIC**. that may develop in the time course of an experiment, must be considered when planning or interpreting data from a spin trapping experiment.
