Abstract
We report on the S(N)2 reaction F- + CH3Br-->FCH3 + Br- in binary clus ters composed of CH3Br and C2F6 in a crossed electron/molecular beam e xperiment. The reaction is induced by resonance dissociative electron attachment to the C2F6 component where the nucleophile F- is generated at an energy (around 3.8 eV) where CH3Br does not capture electrons t o form Br-. The results indicate that the cross section for the S(N)2 reaction is independent of the total excess energy which can be varied between 1.7 and 5 eV in the present system.
