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。

Specifically, we have to take in this exact amount of energy in order to bump the electron up to higher energy level.

特别的，我们严格需要,这么多,来把电子，提升到更高的能级。

This actually relates very closely to what we discussed in class on Friday before the long weekend, and what we were talking about is the energy levels of multielectron atoms.

这实际上与,上个长周末之前的周五的课上,我们所讨论的内容有着密切的联系，当时我们在讨论,多电子原子的能级。
