Now, from your book as well, this is the pz's of the two atomic orbitals forming the bonding orbital.

现在，也是你们书上，这是两个pz轨道,组成的成键轨道。

Absorption of the light allows both the spin and orbital angular momentum of a light beam to be transferred to microscopic particles held within optical tweezers, forming an optical spanner.

光的吸收可以同时导致光束的自旋角动量或轨道角动量转移给微米粒子，就像光学镊子一样引起粒子的转动，从而形成光学扳手。

So, if we have two atomic orbitals coming together from two different atoms and they combine, what we end up forming is a molecular orbital.

如果我们有两个,不同原子的原子轨道,而且它们组合到一起，我们最后就能得到一个分子轨道。

And there's actually a way that we can make predictions here, and what I'll tell you is molecular orbital theory predicts that h e 2 does not exist because it's not stabilized in terms of forming the molecule.

其实我们有一种办法可以做出预测，我要告诉你们的是分子轨道,理论预测He2不存在,因为它形成分子不稳定。
