Appearance potentials and positive-ion mass spectra were determined for IF/sub 5/, BrF/sub 5/, BrF/sub 3/ and ClF/sub 3/. A negative-ion study was made on BrF/sub 3/. The gas samples were subjected to rate of effusion studies in the mass spectrometer sample system and shown to contain diatomic halogen and halogen fluoride impurities. Halogen oxyfluorides were detected in BrF/sub 5/, BrF/sub 3/ and ClF/sub 3/ samples and reaction between O/sub 2/ and BrF/sub 5/ was observed on mixing. Upper limits for ionization potentials were obtained for IF/sub 5/, IF, ICI, Icl, IRr, BrF/sub 3/, BrF, BrCl, ClF/sub 3/ and ClF directly from appearance potentials. Ionization potentials for the radicals BrF/sub 2/ and ClF/ sub 2/ were deduced using supplementary thermochemical data. Ionization potentials of diatomic interhalogens with the exception of BrCl give bond dissociation energies for interhalogen molecule ions approximately equal to corresponding values for neutral molecules.
