摘要：

Infrared spectra of isolated unsaturated rhodium cluster-CO complexes in the region of the CO stretching vibration, ν(CO), are measured using a molecular beam depletion technique. These spectra provide benchmarks for interpreting values of ν(CO) that are found when CO is used to probe Rh surfaces and supported Rh nanoparticles. Supported nanoparticles have shifts of ν(CO) of as much as +100 cm-1 compared to the free clusters measured here, indicative of significant charge transfer to the support.
