The high energy particle bombardment of molecular films adsorbed upon a metal substrate has been investigated via molecular dynamics computer simulations with an empirical many-body potential function constructed for studying reactive dynamics. These calculations identify lateral motion of fragments in the overlayer as giving rise to fragmentation and direct abstraction type reactions. In addition, the importance of substrate mass for particle ejection is identified. These concepts are discussed in detail and experiments are proposed to test these ideas.
