Controlled molecules to investigate ultrafast chemical dynamics in the molecular frame — •Sebastian Trippel — Center for Free-Electron Laser Science, DESY, Hamburg — Center for Ultrafast Imaging, Universität Hamburg

A molecule's chemical behavior is governed by its electronic properties, which are the properties of the involved molecular orbitals. Studying the temporal evolution of these orbitals during the process of a chemical reaction, therefore, provides insight into the fundamentals of chemistry. Furthermore, additional information about the dynamics of a molecular system can be obtained by mapping the position of the individual atoms during a chemical reaction.

State-selected, strongly aligned and oriented molecular ensembles serve as ideal samples to study ultrafast chemistry in the molecular frame. In this tutorial methods for controlling the orientation of molecules in the gas phase as well as techniques to separate various species from a molecular beam will be discussed. Furthermore, state of the art experiments on controlled molecules will be presented.
