Electron spin resonance dating has been applied in Quaternary sciences for more than 30 years. The method is based on the time-dependent accumulation of trapped free electrons and holes in minerals. This article explains the underlying principles of the method and illustrates its contribution to ...
电子自旋共振(electron spin resonance,ESR),又称电子顺磁共振(electron paramagnetic resonance,EPR)。 分子中的电子大多都是成对的,根据泡利不相容原理(Pauli exclusion principle)或包立不兼容原理 ,每个电子对中的电子必为一个自旋向上,一个自旋向下,所以磁性互相抵消。 因此粒子有不成对电子时能表现磁共振的现象。
关键词: 电子自旋共振 , electron spin resonance , ESR , 电子顺磁共振 , electron paramagnetic resonance , EPR 在我们日常生活中常使用的许多塑胶材料,其制程中基本皆是自由基聚合反应生产的。假如可以直接观察到这种自由基聚合反应,将可以获得大量有用的讯息应用在制程或是材料的改良上。因此利用ESR来检测,虽然只...

The reef tracts of Barbados have been investigated by electron spin resonance dating; all parameters necessary for ESR dating (including effective ±-efficiency and thermal stability) were determined without cross checking with another independent dating method. In addition, some U-series analyses were ...
