These molecules burn more cleanly than gasoline, in part because they have fewer, if and, carbon-carbon bonds, and the hydrocarbons they do emit are less likely to generate ozone.

这些分子燃烧起来比汽油更清洁，部分原因是它们的碳-碳键更少或者不存在，而且它们排放的碳氢化合物产生臭氧的可能性更小。

这些分子燃烧起来比汽油更干净，部分原因是它们的碳-碳键更少（如果有的话），而且它们排放的碳氢化合物不太可能产生臭氧。

Because they are not metabolised, these molecules are referred to as "refractory".

因为这些分子不能被代谢，所以被称为“难解质”。

These areas, called cosmic masers, are rich in gas molecules that have the effect of strengthening radio waves.

So, that, for me, was kind of the first connection that what went, "Woah, wait a second, I want to be thinking about these molecules all the way down to the level of individual atoms."

接下来我遇到的一个问题,哇哦，等等，让我想想，是我在学习,有机化学的时候“

Then we're going to actually use MO theory to describe bonding within these molecules, and we'll start with homonuclear diatomic molecules.

然后我们要利用MO理论,来描述这些分子内的成键，我们要讨论同核双原子分子。

These molecules, when mixed with water, organize themselves into neat arrays of cylinders and pinwheels.

These molecules (called chromophores) have been engineered to stop glowing when they come in contact with TNT vapor.

Our brain may only identify one or several of these molecules, but our nose is indiscriminate--it reads them all.
