So, if we look at this graph where what we're charting is the internuclear distance, so the distance between these two hydrogen atoms, as a function of energy, -- what we are going to see is a curve that looks like this -- this is the general curve that you'll see for any covalent bond, and we'll explain where that comes from in a minute.
因此,如果我们来看一看这幅曲线图,这里我们画的横坐标是核间距,也就是这两个氢原子之间的距离,纵坐标是能量,我们看到的这是能量关于核间距的曲线-,这是一条普遍的曲线,在研究任何共价键时你都会遇到,我们马上就会解释一下它是怎么来的。

So, sometimes you'll find the Rydberg constant in different forms, but just make sure you pay attention to units because then you won't mess them up, because this is in inverse seconds here, the other Rydberg constant is in joules, so you'll be able to use what you need depending on how you're using that constant.
有时候你们会发现Rydberg常数,会写成不同的形式,但你们要注意,它的单位就不会弄错了,因为这里是秒的倒数,而另一个Rydberg常数是焦耳,所有你可以根据你要怎么使用,这个常数来选择你需要的常数。
