这是成键和反键。

These are the bonding and antibonding.

反键能量比非成键更高。

Anti-bonding is even higher in energy than non-bonding.

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, just for completeness, is what the antibonding orbital would look like.

youdao

And I am going to superscript it molecular orbital, and this upper one, to indicate that it's antibonding, has the asterisk.

我将给分子轨道加上标，这个上标，表示反键轨道，有一个星号。

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。

So, we'll start today talking about the two kinds of molecular orbitals, we can talk about bonding or anti-bonding orbitals.

今天我们先来,讨论两种分子轨道，我们要讨论成键和反键轨道。
