So let's think of them a little bit more by graphing the amplitude of the wave, and seeing how we can have this constructive interference.
让我们把波的,振幅画出来考虑一下,我们怎么能得到这种相长干涉。
And in either case if we first talk about constructive interference, what again we're going to see is that where these two orbitals come together, we're going to see increased wave function in that area, so we saw constructive interference.
在任何情况下,如果我们首先讨论相长干涉的话,我们同样会看到,当这两个轨道靠拢的时候,我们看到这个区域有波函数增加,所以我们看到的是相长干涉。
The reason that we can talk about this is remember that we're talking about wave functions, we're talking about waves, so we can have constructive interference in which two different orbitals can constructively interfere, we can also have destructive interference.
我们可以这么说的原因是,记住我们说的是波函数,我们说的是波函数,所以我们可以得到相长干涉,这是两个不同轨道会相长干涉,我们也有相消干涉。
So in this case the cross term represents constructive interference between the two 1 s atomic wave functions.
在这种情况下交叉项代表两个,1s原子波函数的相干干涉。
So we can draw that for 1 s a, we can also draw it for 1 s b, and what I'm saying for the molecular wave function is that we have the interference between the two, and we have a constructive interference, so we end up adding these two wave functions together.
所以我们可以对1sa画出它来,我们也可以对1sb画出它来,对于分子波函数我要说的是,它们两者之间会干涉,这里我们有相长干涉,所以我们得到的是波两个波函数加起来。
