N2 - The adsorption states of pyridine on Ru(001) have been studied as a function of exposure and temperature using HREELS. An unusually stable parallel-bonded state I is formed at low coverage below 250 K; at large exposure below 150 K a tilted form II can be additionally formed. A dehydrogenated α-pyridyl state III can be generated by heating multilayers or dense monolayers of type II to 190 K, or by adsorbing at this temperature. Neither III nor II can be formed by heating I.
