@ullrich2003]). Molecules from a supersonic gas jet are crossed orthogonal with ionizing radiation; the resulting fragments (cations and electrons) are projected by an electrostatic field onto time and position sensitive detectors. From the respective times-of-flight and the impact positions on the detector, the momentum vectors of all fragments can be determined in coincidence. As all position and time-of-flight information is stored event by event, possible correlations between fragments can be explored in the offline analysis.\
For the results presented here, X-ray photons were used, provided by the beamline SEXTANTS at the synchrotron SOLEIL (Gif-sur-Yvette, France) [@Sacchi2013]. The synchrotron was used in timing mode in order to obtain a starting time for the time-of-flight measurements. Several measurements with photon energies between 286 eV and 305 eV were performed, with energy resolutions ranging from 80 meV to 300 meV depending on the chosen size of the monochromator exit slits.\
The molecular jet was created by expanding halothane in the gas phase through a 200 $\mu$m nozzle. The pressure before the nozzle was regulated by a needle valve to a value of 50 mbar which is significantly lower than the vapour pressure of halothane at room temperature (300 mbar). The sample was purchased
