Fragmentation dynamics of on collision with a self-assembled monolayer surface

Surface-induced dissociation of doubly charged CS 2 2 + ions colliding with a self-assembled monolayer surface of fluorinated alkyl thiol on Au(1 1 1) crystal has been studied using a beam scattering instrument. Two energetically distinct processes, corresponding to Coulomb explosion and charge transfer induced dissociation have been observed and the latter process dominates the dissociation process.
