The advent of the Free Electron Laser (FEL) delivering unprecedented brilliance and ultra-short pulse duration (a few femtosecond) has opened a door studying the ultra-fast molecular dynamics in the XUV regime employing a Reaction Microscope combined with our novel split-mirror set-up. Using this experimental approach at FLASH we performed a series of XUV pump-probe experiments [1-4] by tracing ultra-fast nuclear wave-packet motion in the D2+(1sσ g) state, isomerization and elimination reactions in Acetylene and Ethylene etc., which pave the way to visualize, control and manipulate molecular reactions in the XUV regime in real time.
