对于你们所熟悉，的氢原子，就是1s轨道能级。

In cases you're extremely familiar with, if it were the hydrogen atom, it would be down in the 1s orbital.

分析分子轨道能级与生化性质和电子光谱的关系。

The relationship between the molecular orbitals energy levels and the biochemistry properties, electron spectrum are discussed.

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。

And this one here, because it is at a higher energy is called antibonding molecular orbital.

And so this lower level is called a bonding orbital, and it is a bonding molecular orbital.

所以能级较低的轨道叫做成键轨道，这就是成键分子轨道。

So if we think about what we would do to actually write out this configuration, we just write the energy levels that we see here or the orbital approximations.

如果我们考虑我们所做的去,实际写出电子构型，我们只是写出我们看到的能级,或者是轨道近似就可以了。
