Particles are flat and Pt(111)-like, but the smaller ones (~1.5 nm in lateral diameter) have Pt-Pt distances that are ~10% less than those in the bulk Pt. When particles are 3 nm in lateral diameter, Pt-Pt distances are the same as in the bulk Pt.

A large discrepancy between relative IR intensities and relative amounts of species present is attributed to intensity transfer. Both conclusions suggest that using IR intensities of adsorbed CO to estimate particle morphology can be problematic.
