Background:

Diatomic molecule interactions with single crystal surfaces are fundamental to heterogeneous catalysis.
Studying these interactions at atomic and femtosecond scales provides deep mechanistic insights.

Purpose of the Study:

To illustrate the current understanding of elementary processes in heterogeneous catalysis.
To highlight key examples of molecule-surface interactions and their catalytic implications.

Main Methods:

Theoretical and experimental investigations of molecule-surface dynamics.
Analysis of processes like dissociative adsorption, associative desorption, and catalytic oxidation.
Utilizing atomic-level and femtosecond time-scale resolution.
