原子光谱,是由原子中的电子在能量变化时所发射或吸收的一系列波长的光所组成的光谱。原子吸收光源中部分波长的光形成吸收光谱,为暗淡条纹;发射光子时则形成发射光谱,为明亮彩色条纹。两种光谱都不是连续的,且吸收光谱条纹可与发射光谱一一对应。每一种原子的光谱都不同,遂称为特征光谱。
按产生光谱的基本微粒的不同,分为: 原子光谱(atomic spectrum):由原子的吸收或发射所形成 的光谱称为原子光谱,原子光谱是由原子外层或内层电子 能级的变化产生的,是线光谱。

So, how many distinct, so again, we're talking about distinct kinetic energies, a spectrum for the element hafnium, 72 and I'll tell you here that it has a z of 72, so you don't have to spend two minutes searching your periodic table.
好,有多少分立的……还是一样,我们讨论的还是不同的动能,铪元素的光谱中出现,而且我来告诉大家铪的原子序数是,这样你就不用因为在元素周期表中找它,而花费两分钟的时间了。
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。
So there are two electron configurations in the n equals one shell, if we follow according to the selection rules that we spelled out last day.
