And...but...but...we have to go a little beyond that.
我們需要進(jìn)一步深入。
Now let me explain why vibrational theory has some sort of interest in it.
現(xiàn)在我來解釋為什么震動理論有一定的道理。
These molecules, as you saw in the beginning, the building blocks had springs connecting them to each other.
這些分子正如你們開始時(shí)看到的是基本組成，它們之間有彈簧連接著。
In fact, molecules are able to vibrate at a set of frequencies which are very specific for each molecule and for the bonds connecting them.
事實(shí)上，分子可以在一定的頻率下震動，每一個不同的分子和不同的連接方式都有特定的頻率。
So this is the sound of the O-H stretch, translated into the audible range.
所以這是O-H鍵發(fā)出的聲音，轉(zhuǎn)化成人耳可以聽到的頻率。
S-H, quite a different frequency.
S-H鍵，有十分不同的頻率。
Now, this is kind of interesting, because it tells you that you should be looking for a particular fact,
現(xiàn)在看來這十分有趣，因?yàn)樗嬖V你，你應(yīng)該尋找一個獨(dú)特的事實(shí)，
which is this: nothing in the world smells like rotten eggs except S-H, OK?
事實(shí)是：除了S-H以外，沒有其他東西聞起來像臭雞蛋。
Now, Fact B: nothing in the world has that frequency except S-H.
第二個事實(shí)就是：除了S-H，沒有其他東西有那樣的頻率。
If you look on this, imagine a piano keyboard.
如果你看到這些，想象一下鋼琴的鍵盤。
The S-H stretch is in the middle of a part of the keyboard that has been, so to speak, damaged,
S-H鍵是在鍵盤的中間部分，可以說鍵盤的那部分損壞了，
and there are no neighboring notes, nothing is close to it.
也沒有其他的音符挨著它。
You have a unique smell, a unique vibration.
你得到的是一個獨(dú)特的味道，一種獨(dú)特的震動。
