摘要：

We studied adsorbed Ru3 (CO)12 and Mo (CO)6 overlayers on Ru(001) and Au/Ru surfaces by infrared reflection-absorption spectroscopy (IRAS) and thermal desorption spectroscopy (TDS). We characterized the C-O stretching mode of both metal carbonyls (4 cm-1 FWHM) and a deformation mode of Mo (CO)6 at 608 cm-1 with an unusually narrow FWHM of 1 cm-1. Both IRAS and TDS data suggest adsorption and desorption of metal carbonyls as molecular species with a preferential orientation in the overlayers. We discuss annealing experiments of Ru3 (CO)12/Ru(001), the interaction of Ru3 (CO)12 overlayers with electrons of up to 100-eV energy, and the interaction of Mo (CO)6 overlayers with 300-nm photons.
