The adsorption and thermal decomposition of azomethane (CH{sub 3}N = NCH{sub 3}) on Pd(111) under ultrahigh-vacuum conditions was studied by temperature-programmed desorption and work function measurements. Adsorbed azomethane is stable on the surface until N-N bond scission occurs at {approx} 250 K. Above 280 K, further decomposition forms H(a) and HCN(a) which subsequently desorb at higher temperatures. No C-N bond dissociation is observed on Pd(111). Thus, both N-N and C-H bond cleavages are observed for chemisorbed azomethane on Pd(111), while only C-N bond cleavage is observed in the gas-phase thermal decomposition of azomethane.
