Electron-induced dissociation of a fluorocarbon adsorbate CF3 (ad) at 4.6 K is shown by Scanning Tunnelling Microscopy (STM) to form directed energetic F-atom ‘projectiles’ on Cu(110). The outcome of a collision between these directed projectiles and stationary co-adsorbed allyl ‘target’ molecules was found through STM to give rotational excitation of the target allyl, clockwise or anti-clockwise, depending on the chosen collision geometry. Molecular dynamics computation linked the collisional excitation of the allyl target to an ‘abortive chemical reaction’, in which the approach of the F-projectile stretched an H–C bond lifting the allyl above the surface, facilitating isomerization from ‘Across’ to ‘Along’ a Cu row.
