In addition to studying molecules and making molecules, some chemists Tim Swager want to detect molecules, and a chemist who likes to detect molecules TNT is Tim Swager. So, Tim Swager's lab has designed sensors that detect vapors, Fido and so they will detect TNT, for example.

除了研究和制备分子,有些化学家想要探测分子,其中的一位就是，他的实验组设计了用来探测蒸汽的感应器,可以用来检测比如说,而且他把化学应用到这个机器人手臂里，他们叫它。

N 2 So any chemist should be able to just look at n 2 and know that it's a triple bond, but that's not something that we've learned how did to do yet, so let's go ahead and start a new topic that's going to allow us to have some sort of sense of what the valence electron configuration, which includes whether something's a single or double or a triple bond can be figured out for any given molecule.

任何一个化学家都应该能够仅仅通过看到2,就知道它有一个三键,但是我们还没学习如何做到这点，因此下面我们就开始进入一个新的主题,它将使我们能够有一定的认识,对于价电子的排布情况，包括可以对任何一个给定分子中的键是单键双键,还是三键作出判断。
