'State-Defining' TAP pulse response experiments

New theoretical results pertaining to TAP vaccum pulse response experiments are described. The theoretical analysis of a ‘state-defining”, experiment, characterized by an insignificant change in the composition and kinetic characteristics of a catalyst, is given. The analytical results for surface coverage distribution are obtained using an irreversible adsorption_diffusion model. It is shown that a one-pulse experiment is a state-defining experiment. For a multipulse experiment, the number of pulses within a state-defining regime is estimated.
