And this spin magnetic quantum number we abbreviate as m sub s, so that's to differentiate from m sub l.
这个自旋磁量子数我们把它简写成m下标s,以和m小标l有所区分。
The other thing that we took note as is what happens as l increases, and specifically as l increases for any given the principle quantum number.
另外一个我们要注意的是,l增加时如何变化,特别是对于某个给定的,主量子数l变化时如何变化。
We use the adjective "Newtonian" but we don't speak of certain writers who are still interested in quantum mechanics as "Newtonian writers."
虽然我们用牛顿主义者这个词“,但是我们不会把那些,对量子力学有兴趣的人称作牛顿主义作家“
b The repulsive term goes as some constant lower case b divided by R to the n. N is not the quantum number.
这种斥力很想一个固定的小写字母,被R到n分开的话,N不是量子数。
We didn't just need that n, not just the principle quantum number that we needed to discuss the energy, but we also need to talk about l and m, as we did in our clicker question up here.
我们不仅需要n,不仅要这个可以,决定能量的主量子数,还需要m和l,就像我们做这道题这样。
1/2 And we have the spin quantum number 2 as plus 1/2 for electron one, -1/2 and minus 1/2 for the electron two.
我们有自旋量子数,对于电子,我们有自旋量子数。
So, we'll take a little bit of a step back after we introduce quantum mechanics, and talk about light as a wave, and the characteristic of waves, and then light as a particle. And one example of this is in the photoelectric effect.
等我们介绍完量子力学后,我们要回过头来讨论下光,作为一种波和它的波动性特征,以及光作为一种粒子,其中的一个粒子就是光电效应。
But now, it has come to light that they are the ones that do get credit for first really coming up with this idea of a spin quantum number, and it's interesting to think about how the politics work in different discoveries, as well as the discoveries themselves.
但现在我们,知道他们是,最先想出自旋量子数,这个概念的人,看各种发现中的,政治学是十分有趣的,和发现本身一样有趣。
R And we abbreviate that by calling it r, l by two quantum numbers, and an l as a function of little r, radius.
我们把它简称为,两个指定的量子数n和,它是半径小r的函数。
So, Lewis structures are really a model for a way to think about what the valence electron configuration is, and as I said, it's not based on quantum mechanics, it's something that Lewis observed far, far before quantum mechanics were discovered.
路易斯结构实际上是一个用来考虑价,电子排布的模型,而就像我说的,它并不以量子力学为基础,而是路易斯在以前发现的,在量子力学出现很早前。
But, as I said before that, we have some more quantum numbers, when you solve the Schrodinger equation for psi, these quantum numbers have to be defined.
但我说了,我们还有,其它的量子数,当你解,psi的薛定谔方程时,必须要,定义这些量子数。
And in order to label the various orbitals, as he called them, m he introduced two more quantum numbers, l and m.
为了给他所说的不同的轨道,标号,他又另外引进了两个量子数,l和。
So if, in fact, we want to describe a wave function, we know that we need to describe it in terms of all three quantum numbers, and also as a function of our three positional factors, which are r, the radius, phi plus the two angles, theta and phi.
实际上,我们想描述波函数,我们知道我们需要,用这三个量子数来描述它,同样,波函数还是,三个位置变量的函数,它们是r半径,还有两个角度theta和。
So really what I want to point out here is as we get more into describing quantum mechanics these quantum dots are one really good example where a lot of the properties of quantum mechanics apply directly. So, if you're interested, I put the Bawendi lab research website onto your notes.
我真正想说的是,随着,我们学习量子力学的深入,这些量子点是很多量子,力学性质得到直接应用的很好例子,如果你们感兴趣的话,我把Bawendi实验室的,网站放到你们的讲义里去。
