What we're going to start with is discussing photoelectron spectroscopy, which is a spectroscopy technique that will give us some information about energy levels in multielectron atoms.

首先，我们将讨论,光电子能谱，通过这种技术,我们能够得到多电子原子的能级信息。

So once we cover it, it will then be fair game to ask these photoelectron spectroscopy or these photoelectric effect questions using the wavelength of the electron.

所以一旦我们涉及到它，问及光电子能谱或者,用电子的波长问及,光电效应是一样的。

And, subsequently, we looked at photoelectron spectroscopy which is a technique that allows us to determine binding energies, ionization energies being just one example.

随后，我们看了光电子谱,这是一种只用一个样品,能够测量结合能，离子化能的技术。

Any one of these different elements could actually produce a photoelectron spectroscopy spectrum that has five distinct lines.

其中任何一种元素,都可能产生,有五条分立谱线的光电子能谱。

All right. So let's go ahead and try an example here in thinking about photoelectron spectroscopy.

好的，下面我们继续来看一个,关于理解光电子能谱的例子。

Since that time, PES we've been able to actually measure these bond strengths by PES, photoelectron spectroscopy.

自从那时，我们就能够用,测量键的强度，光电子能谱。

And this is called photoelectron spectroscopy, and essentially what it is is very similar conceptually to what we were talking about way back in the first couple lectures when we were talking about the photoelectric effect.

也就是光电子能谱，从本质上来讲,这项技术,与我们在最开始的几节课上讲的,光电效应在概念上非常相似。

So, one difference between photoelectron spectroscopy and, for example, the photoelectric effect is that in this case, we're not just looking at one energy level, which is what we were looking at from the surface of a metal, now we're talking about this gaseous atom.

光电子能谱与光电效应的不同点在于，以这种情况为例，我们不只关心一个能级，就像原来在金属表面那样，现在我们研究的是气体原子，所以，我们可以从原子中。

Alright, so we'll pick up with photoelectron spectroscopy on Wednesday.

好的我们周三将会讲解,光电子能谱的专题。

If you see a problem that asks you, for example, the third ionization energy versus taking a second electron out of the 2 s in a photoelectron spectroscopy experiment, those are two very different things.

如果你遇到一个题目问你的是，比如说，是第三电离能,还是在光电子能谱实验中从，2，s，轨道中,拿走第二个电子，这可是两个完全不同的问题。
