摘要：

We obtained IRAS and TDS data for Ru3(CO)12/Ru(001) and Mo(CO)6/Au/Ru systems for metal carbonyl coverages between submonolayer and approximately 20 monolayers. We characterized the C-O stretching mode of both systems (4 cm-1 FWHM) and a deformation mode of Mo(CO)6 at 608 cm-1 (1 cm-1 FWHM). Both IRAS and TDS data suggest absorption and desorption of metal carbonyls as molecular species with a preferential orientation in the overlayers. The IR intensity of the C-O stretch per a C-O bond projected onto the surface normal is approximately twice (five times) larger for Ru3(CO)12 (Mo(CO)6) at submonolayer coverages than for CO/Ru(001) at theta-CO = 0.68.
