We have the line spectra lying out there in the literature, and people read the literature.

这篇文章也涉及到了线光谱,人们都读过这篇文章。

So, let's say we're looking at an element and we have an emission spectra, and we know that it has five distinct different kinetic energies in that spectrum.

比如我们正在研究一个元素,而且我们得到了它的光谱，知道了在它的光谱里,有五个分立的动能。

He measured the line spectra of atomic hydrogen.

测量了氢原子的线光谱。

and he knew this the same way that we saw it in the last class, which is when we viewed the difference spectra coming out from the hydrogen, and we also did it for neon, but we saw in the hydrogen atom that it was very discreet energy levels that we could observe.

那就是,当我们看氢原子发出的光谱时，我们也看了氖气,但我们看到,氢原子能级是分立的，这些，在当时,已经被观察到了,他也都知道。

Because only atomic hydrogen has that set of lines which means I could then take the spectra of gas phase species and use that information to identify.

我在这抬头看看然后离开，那就是氢原子,那就意味着,我可以测定,气相种类的光谱并且运用那个信息来鉴定。

And when we talked about that, what we found was that we could actually validate our predicted binding energies by looking at the emission spectra of the hydrogen atom, which is what we did as the demo, or we could think about the absorption spectra as well.

当我们讨论它时，我们发现,我们可以通过,观察氢原子,发射光谱，来预测，结合能，就像我们在演示实验里做的那样，或者我们也可以观察吸收谱。

So, for example, when people, and we'll talk about this next class, were looking at different characteristics spectra of different atoms, what they were seeing is that it appeared to be these very discreet lines that were allowed or not allowed for the different atoms to emit, but they had no way to explain this using classical physics.

举个例子，当大家看到,不同原子的特征光谱时,他们看到的是一些分离的线,那可以使不同的原子,发射或不发射出去，但是这些无法用经典物理来解释。
