So I show that here, so in green, you have what's called a carboxcylic acid group, a c o o h, which gets converted by s o c l 2 to a c double bond o c l or an acid chloride.

我在这里用绿色表示，我们所说的羧酸族化合物，碳，氧，氧，氢，它被亚硫酰氯转化为,一个碳氧双键与碳氯单键组成的酰氯。

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l和m的值无关。

And so, in this case, l could equal zero, 2 l could equal one or l could equal two.

所以这样的话，l可以等于，也可以等于1或。

Y You don't want to rename them L and R or X and Y right because you want to call them left and right.

你不想把它们重命名为L和R，或者X和,因为你想叫它们为left和。

And if you've typed in l when you should've 1 typed a 1, or a 1 when you should've typed an l, you're likely to miss it. If you've made a mistake with upper and lower case. Things like that. So just be very careful looking at that.

如果你本来想打，1，的时候,却输成了，l，或者打，l，的时候输成了，你很可能注意不到这个错误,如果你把大小写弄混了也是一样,要注意这个错误。

In fact, a French disciple of Hobbes in the next century, a man named La Mettrie, wrote a treatise very much following in the lines of L'Homme Machine Hobbes called L'Homme Machine, " or literally, Man a Machine.

实际上，在下个世纪霍布斯有一个法国的继承者，叫La，Mettrie，他写了一篇论文,在文字上紧紧跟随霍布斯的风格,题目叫，字面上理解，就是“人是机器。

The other main difference that we're really going to get to today is that in multi-electron atoms, orbital energies depend not just on the shell, which is what we saw before, not just on the value of n, but also on the angular momentum quantum l number. So they also depend on the sub-shell or l.

我们今天要讨论的,另一个很重要的区别就是,在多电子原子中，轨道能力不仅仅依赖于，我们以前看到的外层，不仅仅依赖于n的值，而是与角动量量子数也有关系,所以它们也依赖于亚外层或者。

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。

So it's OK to not specify. I want to point out, pz whether you're in the p x, the p y, or the p z, unless a question specifically m asks you to specify the m sub l, which occasionally will happen, but if it doesn't happen you just write it like this.

我想指出的是，无论你在px，py或，除非一个问题特别地,让你指出l下面的，这种情况有时会发生，这样就可以了,但是如果它不做要求你们写成。
