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。
