软 X 射线诱导的激发自旋态捕获的首次观察是在大约 10 秒处对 [Fe(phen)2(NCS)2] 和 [Fe(phen)2(NCSe)2] (phen = 1,10-phenanthroline) 进行的。 45 K，类似于光诱导激发自旋态捕获，但能量更高。在 [Fe(phen)2(NCS)2] 和 [Fe(phen)2(NCSe)2] 的高自旋态和低自旋态中也观察到了软 X 射线光化学，导致形成热不可逆的低自旋态。这种低自旋态的形成速率从低自旋态形成的速率大于从高自旋态形成的速率，并且 [Fe(phen)2(NCSe)2] 中的形成速率也大于 [Fe(phen)2(NCS)2] 中的形成速率。
The first observation of soft X-ray induced excited spin state trapping has been made for [Fe(phen)2(NCS)2] and [Fe(phen)2(NCSe)2] (phen = 1,10-phenanthroline) at ca. 45 K, analogous to light induced excited spin state trapping but at much higher energy. Soft X-ray photochemistry has also been observed in the high- and low-spin states of [Fe(phen)2(NCS)2] and [Fe(phen)2(NCSe)2], resulting in the formation of a thermally irreversible low-spin state. The rate of formation of this low-spin state is greater from low than from high spin, and is also greater in [Fe(phen)2(NCSe)2] than in [Fe(phen)2(NCS)2].
