Abstract

Photoionization of acetone is used to produce the ground electronic state molecular ion with little internal or translational energy. Ion-molecule reactions occurring under thermal energy conditions lead to the formation of the proton bound dimer of acetone at mTorr pressures, the rate constant of which reaction has been measured. The structures of various reactant and product ions are investigated using collision-induced dissociation (CID) reactions at collision energies up to 15 eV. These low-energy CID results are compared with 8 keV CID structures obtained using a conventional high-pressure double-focussing mass spectrometer.
