Název v původním jazyce

Surface Induced Dissociations and Reactions of Acetonitrile Monomer, Dimer and Trimer Ions.

Popis výsledku v původním jazyce

Dissociations and reactions induced by impact of acetonitrile monomer ions (CH3CN+, CD3CN+), dimer ions [(CH3CN)(2)(+), (CD3CN)(2)(+)] and trimer ions [(CD3CN)(3)(+)] on a hydrocarbon-covered stainless-steel surface were investigated over the projectileenergy range of 3-70 eV. Both simple dissociations of the projectile ion and chemical reactions of H-atom transfer from the surface material (followed by dissociations of the protonated projectile ion formed) were observed for the monomer ions. Results obtained for the dimer ions (CD3CN)(2)(+) indicate the formation of the protonated acetonitrile ions via surface-induced reactions in two ways: (i) an intracluster ion-molecule reaction followed by dissociation to form CD3CND+, and (b) a hydrogen pick-upreaction from the surface material during the interaction of the dimer ion with the surface leading to CD3CNH+. A simple model based on the Brauman double-well potential-suggested earlier to explain the occurrence.
