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。

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。

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。
