Abstract
The energy range 300 to 600 cm−1 contains bending and metal–carbon stretching vibrations for carbon monoxide chemisorbed on transition metals. Tunneling spectroscopy reveals vibrations at 436, 519, and 569 cm−1 for carbon monoxide chemisorbed on alumina-supported iron particles. Measured vibrational mode shifts with the isotopes 13C16O and 12C18O suggest that the lower two are bending vibrations and that the highest one is an iron–carbon stretching vibration for the structure Fe=C=O. Comparisons with infrared data on supported iron particles, iron particles in oil, and iron carbonyls suggest the complementary nature of infrared and tunneling spectroscopy in deducing the nature of adsorbed species.
