i(2)PEPICO experimentThe imaging Photoion Photoelectron Coincidence (iPEPICO) endstation is used to study gas phase photoionization. Threshold photoelectron spectra can be recorded for gas phase samples. Internal energy selected ions can be studied by TOF mass spectrometry in coincidence with zero kinetic energy electrons. Thus, very accurate dissociative photoionization thresholds can be determined, which are used in ion cycles to derive thermochemical information.
