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。

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。

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。

So if we name this orbital, this is an anti-bonding molecular orbital So we had bonding and now we're talking about anti-bonding.

这是反键分子轨道,我们有了成键，现在我们讨论反键。

I want to finish this discussion by including the anti-bonding orbital, and this is a tip for you when you're drawing your molecular orbital diagrams, any time you draw a bonding orbital, there is also an anti-bonding orbital that exists.

我想要以包含反键轨道,来结束这个讨论，告诉你们一个,画分子轨道图的小技巧，任何时候你画一个成键轨道，都会存在一个反键轨道。

So we'll start to look at molecules and we'll see if we take two atoms and we fill in our molecular orbital and it turns out that they have more anti-bonding orbitals than bonding, that's -- a diatomic molecule we'll never see.

我们要看开始看一看分子,并且我们会发现如果我们,取两个原子并且填入分子轨道,结果是它们的反键轨道,比成键轨道更多，这就是-一个我们不会看到的二元子分子。

This is sigma star with the antibonding orbital that came from 1s, 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。
