✦ Synopsis

The thermal reaction of on evaporated silver Ðlms was studied in an atmosphere of argon using Raman Fe(CO) 5 spectroscopy. The C-O stretch bands of condensed at 123 K decrease signiÐcantly in intensity after 5 min Fe(CO) 5 of UV irradiation (254 nm) with no appearance of new bands, but further UV irradiation causes little change in the band intensities, suggesting that a monolayer of is formed on the surface by the initial UV exposure. Fe(CO) 5 Upon heating the sample to 204-213 K without UV irradiation, a distinct Raman spectrum is observed in the m(C-O) region. Heating the sample to 270 K leads to further spectral changes. Possible species and structures which can explain these Raman spectra are discussed.
