And as I will explain in a second there are many reasons why this sense hasn't really been elucidated at the molecular level.

难以真正从分子学的角度阐明,这种感官的原因是多方面的,有关这一点,稍后我会另行解释。

My roommate for many years was going to medical school as I was going to graduate school, and we found we had so many interesting conversations about chemistry -- her from the context of practicing and using medications and talking about how they worked on a molecular level, and me talking about my research.

让你们读医学预科的人都转行,我多年的室友在我去读研究生的时候，去了医学院,我发现我们对于化学有过很多有趣的交谈,她会说如何应用药物,如何在分子层面上让它们工作，我则说关于我的研究。

And so this lower level is called a bonding orbital, and it is a bonding molecular orbital.

所以能级较低的轨道叫做成键轨道，这就是成键分子轨道。

Molecular orbital theory, even at this very basic level, allowed us to predict that no, we're not going to see a true bond here, a strong bond.

即使在最基础的层次，分子轨道理论预计，我们不会看到一个键，一个强的键，。

I would say with the aid of an energy level diagram explain the fact that helium is found as atomic gas and not molecular. How about this one?

我要说的是，在能级图的帮助下,可以解释氦气是单原子气体,而不是分子气体这一事实,那么这个呢？
