The order of reactivity by HSiLiF insertion in vacuum indicates the reaction barriers decrease for the same-row element X from right to left and the same-family element X from up down in the periodic table. The insertion reactions in ether are similar to those in vacuum. The energy barriers...
硅化合物的 Si2p 峰分裂可忽略。 观察到两个不同的对称峰(在低通能下)或单个不对称峰(在较高通能下)。 观察到的自旋轨道分裂峰谱图的分辨率会受到元素硅的结晶度/无定形特性的影响。 结晶度越高,自旋-轨道分量的分辨率越高。 无定形程度越高(例如,由 Ar+ 溅射引起),自旋-轨道分量的分辨率越低。
