And there are lots of solutions that chemists come up with -- there's always new techniques that allow us to do this, and these are just some of the first, and we'll go through them in a little bit of detail here.
的情况下研究或者发现它们,化学家们想出了很多的办法,人们发明新的技术来实现它,这些是最早遇到的一些问题,我们要稍微来,研究下它们的细节。
I'm an organic chemist, so I love carbon, it's one of my favorite atoms to talk about, but it would be nice to get to the point of bonding and even reactions to talk about all the exciting things we can think about once we're at that point.
我是个有机化学家,我喜欢碳原子,这是我最喜欢谈论的原子之一,但我更喜欢讲成键,甚至化学反应的概念,一旦到了这之后,我们就可以考虑各种激动人心的事情。
A brilliant chemist.
一个很了不起的化学家。
All right. So, today we're going to be talking about molecular orbital theory, but first I wanted to just mention, in case some of you didn't hear what the Nobel Prize was this morning, and this was in chemistry, it went to three different chemists.
好的,今天我们要讲的是,分子轨道理论,但首先我要说,以免有些同学没有听到,今天早上的诺贝尔奖,这是化学奖,它颁给了3个不同的化学家。
who's a Japanese chemist, Martin Chalfi and then Martin Chalfi who's at Columbia, Robert Chen and Robert Chen UCSD who's at U. C. San Diego.
这是一个日本化学家,还有,他在哥伦比亚大学,还有,他在。
So, that's kinetics -- how fast a reaction will go, and from the perspective of someone who's a biochemist, I'm interested in kinetics and enzyme kinetics, and thinking about molecules that catalyze reactions in the body.
所以这就是动力学,一个反应发生的有多快,从一个生物化学家的角度,我喜欢研究动力学,酶动力学。
So, we being chemists, 1s we'll call that 1 s instead of 1, 0.
作为化学家,我们把1,0,0叫做。
And the reason I was able to do that and keep with what my original intentions were was to have a career that was the fulfilling, in terms of helping people and being engaged in science, is all of a sudden I realized, as chemists, we can think about better ways to build molecules that are important for making medications.
我能够这么做,并且能不和我原来的打算冲突,是因为我的职业很有意义,能帮助他人,又和科学相关,于是突然我意思到,作为一个化学家,我们可以思考出更好的办法,制造出在制药方面十分有用的分子。
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。
So, my final example is from Alan Davidson's lab, and Alan is an inorganic chemist -- he loved those transition metals and they're unique properties, and he designed this compound, it's called Cardiolite, Cardiolite and it's used in heart imaging.
最后一个例子是Alan,Davidson实验室,他是个无机化学家-,他喜欢研究过渡金属,和它们的奇特性质,他设计了这种化合物,叫做。
