Because odorants like acetophenone and d-acetophenone mainly differ in their vibration patterns , the most plausible explanation , he says , is that flies can " smell molecular vibrations . "
Odorants such as acetophenone and deuterated acetophenone , for example , have the same molecular structure ; one is just built from a slightly heavier hydrogen atom , known as deuterium .
例如苯乙酮和氘苯乙酮气味分子具有相同的分子结构,其中一个是用称为重氢的氘原子构成。
Now we produce 5 groups of series organic chemicals , which includes fluoro aniline , chloro aniline , phenol , kenzonitrile , acetophenone , trifluoro methoxy , and other intermediates of pharmaceutical , pesticide and dyestuft .
