Thin Film Generation of Novel Materials, Mass Spectrometry of Clusters

Our group was interested in utilizing state-of-the-art mass spectrometric techniques to explore chemical reactions within gas-phase clusters (i.e., {CH₃OH}_n{H₂O}H⁺, {C₂H₄}_n⁺, etc.). We had five different experiments in order to study a wide variety of chemical systems:

1. a continuous cluster beam source mated to a high resolution triple quadrupole mass spectrometer,
2. a pulsed cluster beam source used in conjunction with a reflectron time-of-flight mass spectrometer for multiphoton studies,
3. a metal cluster source used for the generation of thin films, utilizing a quadrupole mass spectrometer for beam diagnostics,
4. a triple quadrupole mass spectrometer for the study of fullerene (C60) ion chemistry,
5. a ZAB-SE tandem mass spectrometer which is used to conduct dissociation experiments on metallofullerene species (Sc@C60).
