Abstract

The PIFCO technique in which mass-selected photoion—fluorescence photon coincidences are counted, was used to investigate whether I2+, IBr+ and ICl+ fluoresce. Measurements were made of lifetimes and fluorescence quantum yields of electronic excited states of these ions. Emission was discovered for I2+ and IBr+, but ICl+ apparently does not fluoresce. Information on the radiative properties of Br2+ was obtained as a by-product of the work on IBr+. Fragment ion kinetic energy releases were determined and provide information on dissociative ionization processes in the halogen and interhalogen ions studied.
