So, there's two kind of cartoons shown here that give you a little bit of an idea of what this quantum number tells us.
这里展示的两个图片,可以让你们对,这个量子数有些概念。
So, what he did was kind of impose a quantum mechanical model, not a full one, just the idea that those energy levels were quantized on to the classical picture of an atom that has a discreet orbit.
还不是完整的,只是这些能级,是量子化的概念,作用到原子有分立轨道的经典原子模型上,当他做了一些计算后,他得到有个半径,他算出来。
I am not only going to say that we have quantization in the motion.
我并不是说,我们只在概念上有量子学。
We remember that Lewis structures are an idea that are pre-quantum mechanics.
我们记得路易斯结构是一个,早于量子力学的概念。
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。
So quantization of radiation was already established as of about 1900.
所以辐射的量子化概念,在1900年左右就建立了。
So we can completely describe an orbital with just using three quantum numbers, but we have this fourth quantum number that describes something about the electron that's required for now a complete description of the electron, and that's the idea of spin.
所以我们可以用3个,量子数完全刻画轨道,但我们有这第四个量子数,来完整的,描述电子,这就是自旋的概念。
