现在画分子振动能级，这不一定是这样，我们假设这是双原子分子。

So now I'm going to draw vibrational energy levels inside the molecule. Let's imagine, it wouldn't need to be this, ut let's imagine it's just diatomic molecules.

这就是我们上一节课，所看到的结果，所处理分子振动模型，和计算振动能，在同一个模型上。

So that's what we saw last time in the case of both the conformational model that we treated and the vibrational energies of molecules onto which that same model maps.

对于大许多分子，振动能对于kT来说很大。

Again, in the case of many molecules, the vibrational energy is pretty high compared to kT.
