Doubly charged CO2 clusters formed by ionization of doped helium nanodroplets.

Daxner M, Denifl S, Scheier P, Echt O - Int J Mass Spectrom (2014)

Bottom Line: Helium nanodroplets are doped with carbon dioxide and ionized by electrons.Thanks to the high mass resolution, large dynamic range, and a novel method to eliminate contributions from singly charged ions from the mass spectra, we are able to observe doubly charged cluster ions that are smaller than the ones reported in the past.The likely mechanism by which doubly charged ions are formed in doped helium droplets is discussed.

ABSTRACT

Helium nanodroplets are doped with carbon dioxide and ionized by electrons. Doubly charged cluster ions are, for the first time, identified based on their characteristic patterns of isotopologues. Thanks to the high mass resolution, large dynamic range, and a novel method to eliminate contributions from singly charged ions from the mass spectra, we are able to observe doubly charged cluster ions that are smaller than the ones reported in the past. The likely mechanism by which doubly charged ions are formed in doped helium droplets is discussed.
