In this research project, the kinetics of ion-molecule reactions in the gas phase as a function of the effective ion temperature will be investigated using a high-energy ion mobility spectrometer (HiKE-IMS) with selective ion sources. In order to generate defined ion populations, a hollow cathode ion source compatible to the HiKE-IMS will be realized within the scope of this research project. In addition, an implementation of a laser ionization source in the ionization region of the HiKE-IMS is planned, in which the ionization of molecules is achieved by resonant multiphoton excitation. This will allow a detailed investigation of reaction rates and reaction rate constants.
