Using a rapid [[ultrafast]] [[laser]] technique (consisting of [[ultrashort pulse|ultrashort]] laser flashes), the technique allows the description of reactions on very short time scales – short enough to analyse [[transition state]]s in selected chemical reactions.<ref>{{cite web|title=Press Release: The 1999 Nobel Prize in Chemistry|date=12 October 1999|url=http://nobelprize.org/nobel_prizes/chemistry/laureates/1999/press.html|publisher=Nobelprize.org|access-date=12 February 2011}}</ref> [[File:Ahmed_Zewail_1986.png|alt=Ahmed_Zewail_1986|thumb|218x218px|Zewail in 1986]]
