我们也知道振动能的配分函数。

We also know what the vibrational partition function is.

youdao

都有对应的配分函数，每个自由度。

Then you can have a partition function for each of these degrees of freedom.

youdao

对单个分子的配分函数本身也适用。

You can also look at the molecular partition function itself.

youdao

现在我们来计算分子的配分函数。

So now let's figure out our molecular partition function.

youdao

总配分函数,是这两者之积。

Q And now the total system partition function is the multiplication of these two.

youdao

现在qi是分子总配分函数。

Now, qi is just the total molecular partition function.

youdao

系统的配分函数用Q标记。

And the system partition function is labeled big Q.

youdao

好，这就是分子配分函数。

OK. So this is your molecular partition function.

youdao

我们可以把配分函数写成，对能级的求和。

We can write the partition function as a sum over energy level.

youdao

这是电子的配分函数。

This is the electronic partition function.

youdao

所以振动配分函数也没有什么变化。

So then nothing is going to change in the vibrations.

youdao

由配分函数求出二元系统的物态方程。

Then the equation of state for binary system is developed.

youdao

我们用的4种分子的振动配分函数都是。

For all four of the molecules.

youdao

而不是分子配分函数。

Not just the molecular one.

youdao

同样的，对构型部分,也是分子构型配分函数的N次方。

You also have the system partition function for the configurations.

youdao

上面是生成物，下面是反应物，非常简单，因为我知道如何计算所有这些配分函数。

Products, reactants. Pretty simple, because I know how to calculate all this stuff.
