So what that means is that we're limited in any atom to having two electrons per orbital, right, because for any orbital we can either have a spin up electron, a spin down electron, or both.

这意味着在一个原子内,每个轨道上可以有两个电子，对吧，因为对任何轨道,我们可以有自旋向上或者自选向下或者两者都有。

Angular momentum has two key components: spin angular momentum and orbital angular momentum.

角动量有两个分量：自旋角动量和轨道角动量。

The total energies, spin multiplicities, charge distribution, bond orders, the front molecular orbital compositions and orbital energies have been obtained.

得到了它们的基态能量，基态自旋多重度，分子轨道组成与能级，电荷分布与键序。
