This is sigma star with the antibonding orbital that came from1s, and it is a molecular orbital. 这是sigma星,来自于1s的反键轨道,它是一个分子轨道。
It turns out that the antibonding orbital is a little bit higher from the atomic orbital level than the bonding orbital is lower. 这证明了,反键轨道,比原子轨道高,成键轨道比原子轨道第。
And this one, just for completeness, is what the antibonding orbital would look like. 然而这个,只是为了其完全性,把反键轨道也表示出来。
And this one here, because it is at a higher energy is called antibonding molecular orbital. 这里的这个,因为处在一个较高的能级,被叫做反键分子轨道能级。
