  • In contrast, if we're taking the wave function and describing it in terms of n, l, m sub l, and now also, the spin, what are we describing here?

    相反,如果我们考虑一个波函数,然后用n,l,m小标l,还有自旋,我们描述的是什么?

    麻省理工公开课 - 化学原理课程节选

  • 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。

  • And the complete description, as I said, n l m is from n l and m.

    我说过完整的描述,需要。

    麻省理工公开课 - 化学原理课程节选

  • So let's just think exactly what this means, and that means that if we take away function and we define it in terms of n, l and m sub l, what we're defining here is the complete description of an orbital.

    让我们来考虑一下这是什么意思,这是说如果我们不考虑波函数,而是用n,l,m下标l来定义它,我们定义的,是一个轨道的完整描述。

  • Just by n, l, m, s is inadequate.

    仅仅靠n,lm,s是不够的。

    麻省理工公开课 - 固态化学导论课程节选

  • No, we can't. Because if l equals 1, we can not have m sub l equal negative 2, right, because the magnetic quantum number only goes from negative l to positive l here.

    不行,因为如果l等于1,ml的值不可能等于-2,对吧,因为磁量子数的值,这时只能从-1到1

    麻省理工公开课 - 化学原理课程节选

  • So, if we think of just an example, 2 we could say that 4 l equals 2, what would be our lowest value of m sub l?

    举个例子,如果我们说l等于,那m小标l,最小值是多少?

    麻省理工公开课 - 化学原理课程节选

  • And in order to label the various orbitals, as he called them, m he introduced two more quantum numbers, l and m.

  • s We are back over to E as a function of n, l, m and s, only we got there through this other torturous route.

    我们回到将E作为函数n,l和,只要我们解决了这个烦人的路径。

    麻省理工公开课 - 固态化学导论课程节选

  • So the allowed values for m sub l 0 are going to be negative l, all the way up to 0, l and then up to positive l.

    所以m小标l的可能值,是从负l,一直到,然后到正。

    麻省理工公开课 - 化学原理课程节选

  • So, our next level up that we can go is going to be the n equals 2 energy level, but we also have an l and an m value, 0 so our lowest l is going to be a there.

    所以下一个能量,是n等于2的能级,但我们还有lm的值,所以我们最低的l等于。

    麻省理工公开课 - 化学原理课程节选

  • So finally, if we talk about our last example of when n is going to be equal 2, l -1 and then minus 1 for m.

    最后我们要讲的,这个例子,是n等于2时,等于1,we,can,have,2,,1,for,l,而m等于。

  • So when we talk about a wave function squared, n l m he wave function, any one that we specify between n, l and m, at any position that we specify based on r, theta, and phi.

    一个波函数,的平方时,对特定,特定位置r,theta,phi波函数,取平方,如果我们取平方。

  • PROFESSOR: OK. We can have n 4, l 3, and then, sure, we can have m sub l equal negative 2 if l equals 3 What's the second value of l that we can have?

    教授:嗯,我们有n4,l3,然后我们有ml等于-2,如果l等于3,l可以有的第二个值是多少?

    麻省理工公开课 - 化学原理课程节选

  • Yup. So m sub l could equal 2 negative 2, negative 1, 0, 1 or 2.

    嗯,m下标l可以等于,2,-1,0,1,或。

    麻省理工公开课 - 化学原理课程节选

  • So we could have five values of m sub l.

    所以它可以取5个值。

    麻省理工公开课 - 化学原理课程节选

  • Again, the reason for that is because the energy only depends on the n value here, it doesn't depend on l or on m.

    因为,能量,只和n的值有关,与lm的值无关。

  • But you can look at manuscripts of the early eleventh century and see people singing Ps and Ls and Os and Ms and things like that.
