中文简介:
//“而且要超越它真的需要一些密集的量子力学。所以,我们将继续使用s和p块。我们看到,如果我们有两个原子轨道,当它们混合形成分子轨道时,它采取了这种椭球形状//我们称之为sigma轨道。而且,sigma轨道的特征是你从一个核到另一个核具有连续的电子密度。我们说没有假期;恒定的电子密度//我们可以合成一个轨道和一个轨道,例如在氟化氢的情况下。在s加p的情况下,最终会得到一个看起来像这样的轨道。而且,它也被称为sigma轨道,因为再次,如果你从一个核看到另一个核,有连续的电子密度,没有假期....“//
课程简介: //"And to go beyond that really requires some intensive quantum mechanics. So, we're going to stay with s and p-block. And we saw that if we had two atomic s-orbitals, when they blended to form the molecular orbital, it took on this sort of the ellipsoidal shape.// //We called that a sigma orbital. And, the characteristic of the sigma orbital is that you have continuous electron density from one nucleus to the other. We said no holidays; constant electronic density.// //We could then combine an s orbital and a p orbital, as for example in the case of hydrogen fluoride. In the case of s plus p, will end up with an orbital that looks something like this. And, it is also termed a sigma orbital because, again, if you look from one nucleus to the other, there is continuous electron density, no holidays...."//
