Positive ionization and electron attachment of hexafluoropropylene oxide in different cluster environments
Original language description
The hexafluoropropylene oxide, C3F6O (HFPO), is commonly used in technological processes involving low-temperature plasmas. In relevance to such processes, we investigate the electron ionization and attachment to HFPO molecules in various cluster environments. Either pure (HFPO)N clusters or the clusters deposited on larger argon nanoparticles (HFPO)N·ArM are generated in molecular beams in vacuum. The cluster beam is intercepted with a beam of either slow (0–15 eV) or faster (70 eV) electrons, yielding negative or positive ions, respectively, and their mass spectra are recorded. Qualitatively, the spectra of free and Ar-deposited clusters are similar, exhibiting the same ion fragments. The cluster environment suppresses the fragmentation after ionization for both positively and negatively charged clusters, namely, the parent ions (HFPO)n+/− are present in the spectra. The fragmentation is more suppressed in the Ar-deposited clusters. In both the positive ionization and attachment, new fragmentation channels or ion-molecule reactions in the clusters lead to production of new fragments not observed in the gas phase. Mechanisms of these reactions and ionization processes are discussed.
