Then we're going to actually use MO theory to describe bonding within these molecules, and we'll start with homonuclear diatomic molecules.

然后我们要利用MO理论,来描述这些分子内的成键，我们要讨论同核双原子分子。

So, I will point out, in terms of MO theory, because it rigorously does take into account quantum mechanics, it starts to become complicated once we go beyond diatomic molecules.

我要指出的是，对于MO理论，以为它严格的遵守量子力学，所以一旦超过双原子分子,就变得十分复杂了。

All right, so one thing that I first want to point outabout MO theory that is a big difference from Lewis structures, is that in MO theory valence electrons are de-localized over the entire molecule.

好了，对于MO理论低一点要指出的,是它和Lewis有着很大的区别，在MO理论里,价电子在整个分子里是去局域化的。

This was something we could not predict using Lewis structures, but we can predict using MO theory that we have a radical species here.

这是我们从Lewis结构里不能预测的，但我们可以用分子轨道理论,预测自由基。

So that's a really important type of an application that we can use MO theory for that we weren't able to do with our Lewis structures.

这是MO理论,在Lewis结构,不能用时的,非常重要的应用。

And specifically, MO theory is the quantum mechanical description of wave functions within molecules.

特别的，MO理论是,分子内波函数的描述。
