Surface-induced Reactions and Dissociations of Small Acetone, Acetonitrile and Ethanol Cluster Ions:Competitive Chemical Reactions, Dissociation Mechanisms and Determination of Dissociation Energy.
Original language description
Using a recently commissioned tandem mass spectrometer system, BESTOF, we have carried out systematic investigations (using also deuterated molecules) on the interaction of various molecular cluster ions (including stoichiometric acetone and acetonitrilecluster ions and protonated ethanol cluster ions) with a hydrocarbon-covered stainless steel surface. Besides observing competitive chemical reactions for the stoichiometric cluster ions driven by the energy transfer in the surface collision (intra-cluster reactions versus surface H-atom pick-up reactions), we were able to see clear evidence that unimolecular dissociation kinetics determines the production of the observed decay patterns in collision energy-resolved mass spectra (CERMS). From characteristic shifts in these CERMS we can deduce corresponding binding energies, i.e., D((CD3CN2+-CD3CN = 0.66 eV, D((C2H5OH2H+-C2H5OH = 0.95 eV, and for the protonated dimer D((C2H5OH)H+-C2H5OH = 1.6 eV.
