So any time you have two atoms bonding, the bond axis is just the axis that they're bonding along.
任何时候如果你有两个原子成键,键轴就是它们成键的方向。
So that is the bond axis it's just the axis between the two nuclei.
这就是键轴,它就是两个原子核之间的轴。
The first one will be above and below the bond axis is where we'll see the electron density, and the second will be perpendicular to that, so it will be a density in front of and behind the bond axis.
第一个是在键轴之上和之下,我们可以看到电子密度,另外一个垂直于它,所以在键轴之前和之后有电子密度。
So any time you have two atoms bonding, the bond axis is just the axis that they're bonding along.
任何时候如果你有两个原子成键,键轴就是它们成键的方向。
Remember this is our bond axis here, and you can see there is this area where the wave function is equal to zero all along that plane, that's a nodal plane.
记住这是我们的键轴,你可以看到在这些区域,波函数在这个面内全都是零,这是节点面。
So even though we see a nodal plane down the center, I just want to really point out that it's only when we have a nodal plane in the internuclear or the bond axis that we're calling that a pi orbital.
虽然在中间有个节面,我想要指出的是,只有节面在核间轴,或者键轴上时,我们才叫它π轨道。
