摘要：

Molecular oxygen states present at Ag(111) surfaces when dioxygen is coadsorbed with ammonia at 80 K are characterised by vibrational loss features at 1488 and 1640 cm(-1) The former is suggested to be associated with the NH3 ... O-2(delta-) complex, a key intermediate in the oxidation pathway.
