Abstract

Experiments on the catalytic reduction of NO with CO on a Pt(100) surface reveal attractive interaction between pulses leading to the eventual merging of two pulses to a single one. The results can be reproduced with a realistic reaction-diffusion model which yields a negative slope in the dispersion relation over a large range of the interpulse distance.
