Collision-Induced Dissociation And Ion Mobility Mass Spectrometry Of Au30(S-Tbu)18 Nanoclusters, Christopher Hood
Honors Theses
Collision Induced Dissociation (CID) and Ion Mobility Mass Spectrometry (IM-MS) are methods used to understand the structural arrangement and stability of large molecules. In this study, the gold nanocluster Au30(S-tBu)18 was dissociated at varying Trap collision energies, and drift time vs mass spectrometry data was plotted to determine the order of cluster fragmentation. Comparing Au30(S-tBu)18 data to that of Au25(SCH2CH2Ph)18, the only current nanocluster published with IM-MS data, two distinctly different dissociation patterns were seen. Unlike the linear CID fragmentation of Au …
