据英国 New Scientist1993年6月19日报道,液体中化学键形成所需时间第一次得到测定。加州大学欧文分校的阿普卡林(Ara Apkarin)和他的同事研究了氯化氙和一个氙原子之间的键。他们发现,该键的形成需330飞秒,这看起来可能很快,但如果用氢原子代替氙原子,此过程可能只需30飞秒,因此无法测量。 According to the British New Scientist reported on June 19, 1993, the time required for the formation of chemical bonds in a liquid was determined for the first time. Ara Apkarin of the University of California, Irvine, and his colleagues studied the bonds between xenon chloride and a xenon atom. They found that the formation of the bond required 330 femtoseconds, which may seem fast, but if hydrogen atoms were used instead of xenon atoms, the process could be as fast as 30 femtoseconds and could not be measured.
