电子亲和能

使用不同的基组计算团簇YO的电子亲和能和电离能。

Different basis sets were used to calculate the electron affinity ( EA ) and ionization potential ( IP ) of YO .

但是，电子亲和能既可以是负的，也可以是正的。

Electron affinity , however , can be either negative or it can be positive .

CN取代的PDI具有较高的电子亲和能，并且其对应的化合物A-CN和B-CN具有较小的电子重组能和空穴重组能。

Compound A-CN and B-CN has a smaller hole and electron reorganization energy , and their electron affinity higher .

要想答对这个问题，你只需要好好想一想，电子亲和能的真正意义。

To answer this question you just really want to think about what does electron affinity means .

这意味着氮的电子亲和能很低，它实际上并不愿意得到一个电子。

So this means nitrogen has low electron affinity , it doesn 't actually want to gain an electron .

那么，你认为稀有气体的电子亲和能，应该是一个高的正值，一个低的正值，还是一个负值？

So do you think noble gases would have a high positive electron affinity , a low positive , or negative electron affinity ?

看来大部人都想到了，如果你翻翻讲义的话，它们的电子亲和能确实是负的。

So most of you recognize , if we switch back to the notes , that they do have a negative electron affinity .

通过孤立给体和受体的几何构型优化，计算了给体的电离能和受体的电子亲和能。

After geometric optimizations of the isolated donor and acceptor , the ionization potential of the donor and the electron affinity of the acceptor have been calculated .

那么，我们可以想一想电子亲和能的，周期性规律是怎样的，就像我们刚才分析电离能那样。

So , we can think about trends in electron affinity just like we did for ionization energy , and what we see is a similar trend .

详细地分析了团簇的结构特征，平均结合能，垂直电离势，垂直电子亲和能，电荷转移以及成键特征。

Structural features , binding energies , vertical ionization potentials , vertical electron affinity , charge transfers , and binding characters were evaluated for each Au & Ni binary cluster .

我们讲了电离能的，电子亲和能的，还讲了电负性的，也就是前两个的组合，最后讲了原子半径的。

We talked about ionization energy , electron affinity , we talked about electronegativity , which is just kind of a combination of the first two , and then ended with atomic radius here .

然后我们再开始讲元素周期表，我们会看到很多周期性规律，比如电离能，电子亲和能，电负性以及原子半径。

We 'll then take a turn to talking about the periodic table , we 'll look at a bunch of periodic trends , including ionization energy , electron affinity , electronegativity and atomic radius .
