Using a temperature-controllable frequency ion trap, we investigated the reaction kintetics of vanadium oxide cluster anions and cations with oxygen, sulfur dioxide and water under multi-collision conditions. The ion trap is inserted into a tandem quadrupole mass spectrometer to investigate mass selected cluster ions. By mass selected detection of the formed reaction products as a function of trap temperature and trapping time we were able to get informations about reaction paths and the kinetics of product formation.
