This article described a theoretical approach for treating chemisorpti
on and surface reactions on metals. Electronic structures are describe
d by an nb initio embedding formalism that permits an accurate determi
nation of reaction energetics and adsorbate structure. Chemisorption e
nergies, adsorbate structures, and the reaction of coadsorbed species
are reported for methane thiolate on Ni(111) to illustrate the method.
