Clusters of boron tribromide molecules undergo photoionization by excimer laser radiation (193 and 248 nm) and mass analysis in a time-of-flight mass spectrometer.  Clusters in the BnBr3n+ and BnBr3n-1+ series are mass-selected with a time-based double-pulse mass gate and further analyzed by photofragmentation (1064, 532, 355 nm).  The fragmentation patterns provide information about structures of parent cluster ions.
