瑞典皇家科学院把1999年的诺贝尔化学奖授予加州理工学院的化学和物理教授AhmedH.Zewail,以表彰他为超快光谱学开发的一项技术。1987年,Zewail研究组率先开发了这一系统,它用飞秒脉冲激发分子,数十飞秒后测试,可使研究人员观察到化学反应进行过程中快速振动变化和电荷变化,再也 The Royal Swedish Academy of Sciences awarded the 1999 Nobel Prize in Chemistry to Ahmed H. Zewail, a professor of chemistry and physics at the California Institute of Technology, in recognition of his development of ultrafast spectroscopy. In 1987, Zewail’s team pioneered the development of a system that uses pulses of femtosecond pulses to excite molecules and dozens of femtosecond tests that allow researchers to observe rapid changes in vibration and charge during chemical reactions.
