In combination with a femto-second Laser our ColTRIMS-technique can give interesting insights in the timedependent behaviour of molecules. Because of excitation or ionization the molecule can show different reactions like shrinking or Coulomb-explosion, which can be measured by our detectors.

So far we investigated the following subjects:

H2+ in strong fields	Double Ionization of N2 and O2
Direct Determination of Absolute Molecular Stereochemistry in Gas Phase by Coulomb Explosion Imaging	Attosecond movies without attosecond pulses: Electron motion in dissociating H2+
