摘要

对多晶L-α-无水天冬酰胺（L-Asn）辐照形成的顺磁中心进行了EPR研究。γ辐照样品在室温下的EPR光谱显示存在三种类型的顺磁中心。基于文献数据，提出了三个自由基物种的可能形成机制。热退火过程中自由基消失的动力学表明了一个复杂的机制。

Kinetics of the thermal disappearance of radicals formed during the radiolysis of L-α-anhydrous asparagine

An EPR study of paramagnetic centers formed by irradiation of polycrystalline L-α-anhydrous asparagine (L-Asn) was performed. The EPR spectra of gamma irradiated samples at room temperature, shown the presence of three types of paramagnetic centers. A possible mechanisms of formation for the three radical species is suggested, based also on literature data. The kinetics of the disappearance of radicals during thermal annealing indicated a complex mechanism.
