Abstract
The collision of energetic gas phase particles with adsorbed species can induce a variety of processes. Events of this
kind can play an important role in the mechanisms governing heterogeneous catalysis at high pressures and elevated
temperatures. Two collision induced processes (CIP) are described in this article. The first process discussed is
collision induced desorption (CID). The CID of N2 from Ru(001) is considered at both low and high coverage ranges.
The interpretation of the experimental data using molecular dynamics (MD) simulations leads to the introduction of
