I went searching for a type of molecule, any molecule, that would have that vibration and that -- the obvious prediction was that it should absolutely smell of sulfur.  我开始寻找一种分子，任何分子会有那种震动的分子--明显地，我预测那种分子一定闻起来像硫。

　　If it didn't, the whole idea was toast, and I might as well move on to other things. 如果闻起来不像，那么整个想法就是糟糕透顶，我最好还是去做别的事情。

　　Now, after searching high and low for several months, I discovered that there was a type of molecule called a Borane which has exactly the same vibration.  在到处寻找几个月后，我发现有一种叫做硼烷的分子和硫有一模一样的震动。

　　Now the good news is, Boranes you can get hold of.  好消息是硼烷是可以获取的。

　　The bad news is they're rocket fuels. Most of them explode spontaneously in contact with air,  坏消息是它是火箭燃料，大部分情况下它们在遇到空气的瞬间就会爆炸，

　　and when you call up the companies, they only give you minimum ten tons, OK?  而且你打电话向公司询问，他们会告诉你你最少要买10顿。

　　So this was not what they call a laboratory-scale experiment, and they wouldn't have liked it at my college. 所以这不是一个实验室规模的实验，我所工作的学院也不会喜欢这个主意。
