Complex molecules often exhibit different conformers (structural isomers) even in the conditions of a cold (≈1 K) molecular beam. Different conformers usually have different properties and can be spatially separated with a strong inhomogeneous electric field. Furthermore, these controlled molecules are ideal samples for strongly linking the molecular and laboratory frames through laser alignment and orientation

The project of Thomas focusses on the creation of strongly 3D-aligned and oriented samples of individual conformers in order to investigate their ultrafast interconversion dynamics. This can be done by coherent X-ray diffractive imaging, time-resolved X-ray spectroscopy, and X-ray-induced molecular-frame photoelectron angular distribution. Along these lines, Thomas is involved in the setup of appropriate infrastructure at the European XFEL within the COMO enduser consortium.
