拓展知识:homo和lumo什么意思
这两个名词属于前线轨道和前线电子的概念,是由福井谦一提出的,并获1981Nobel奖。
已占有电子的能级最高的轨道称为最高已占轨道,用HOMO表示。未占有电子的能级最低的轨道称为最低未占轨道,用LUMO表示。HOMO、LUMO统称为前线轨道,处在前线轨道上的电子称为前线电子。
HOMO:Highest Occupied Molecular Orbital
LUMO:Lower Unoccupied Molecular Orbital
前线轨道理论认为:分子中有类似于单个原子的“价电子”的电子存在,分子的价电子就是前线电子,因此在分子之间的化学反应过程中,最先作用的分子轨道是前线轨道,起关键作用的电子是前线电子。
这是因为分子的HOMO对其电子的束缚较为松弛,具有电子给予体的性质,而LUMO则对电子的亲和力较强,具有电子接受体的性质,这两种轨道最易互相作用,在化学反应过程中起着极其重要作用。
