parameters for inversion of 1,2,2-trimethylaziridine have been evaluated by the line-shape method for the temperature-dependent nmr spectra of the neat liquid and solutions in acetone, benzene, and chloroform. The previously reported activation energy for inversion of this substance is substantially too low. There appears to be a striking difference in activation energy, but not in rate, for inversion in acetone
1,2,2-三甲基氮丙啶转化的动力学参数已通过线形法对纯液体和丙酮、苯和氯仿溶液的温度相关核磁共振谱进行了评估。先前报道的这种物质转化的活化能太低了。对于丙酮和氯仿的转化,活化能似乎存在显着差异,但在速率上没有显着差异。
