The clusters discussed in this work were formed by spraying a 5mM iodic acid/ 10mM ammonium hydroxide solution in a 50/50 water/methanol solution with 0.1% formic acid on an electrospray ionization (ESI) source. These clusters were generated on two different instruments: a Thermo Scientific LTQ XL linear trap mass spectrometer and a home-built guided ion beam/ion trap/tandem time-of-flight (TOF) photofragmentation mass spectrometer discussed in detail in previous work. The mass spectrum displayed in Figure was recorded on the LTQ XL, which provided insight into the cluster compositions derived from this mixture. Further analysis took place through mass spectrometry coupled to infrared (IR) spectroscopy carried out on the home-built guided ion beam/ion trap/tandem time-of-flight (TOF) photofragmentation mass spectrometer.
