C-O Bond Dissociation and Induced Chemical Ionization Using High Energy (CO₂)_n⁺ Gas Cluster Ion Beam.

ABSTRACT: A gas cluster ion beam (GCIB) source, consisting of CO₂ clusters and operating with kinetic energies of up to 60 keV, has been developed for the high resolution and high sensitivity imaging of intact biomolecules. The CO₂ molecule is an excellent molecule to employ in a GCIB source due to its relative stability and improved focusing capabilities, especially when compared to the conventionally employed Ar cluster source. Here we report on experiments aimed to examine the behavior of CO₂ clusters as they impact a surface under a variety of conditions. Clusters of (CO₂)_n⁺ (n = 2000~10,000) with varying sizes and kinetic energies were employed to interrogate both an organic and inorganic surface. The results show that C-O bond d
