The dissociative chemisorption of pyrrole molecules on Si(111)-(7×7) was investigated using HREELS, TDS, STM, and theoretical calculation. The pyrrolyl radical and H atom formed via the N-H bond cleavage were found to be bonded to the adjacent adatom and rest atom, respectively. Analyses of the spatial distribution of reacted adatoms showed that the adsorption is highly site selective.
