Na-induced bonding and bond-length changes for CO on Pt(111): A near-edge x-ray-absorption fine-structure study
Near-edge x-ray absorption fine-structure studies above the C and O K edges for CO on Pt(111) reveal a 4-eV shift of the sigma shape resonance when Na(0.2 monolayer) is coabsorbed. This allows determination of a Na-induced (0.12 +- 0.03)-A expansion of the C-O bond. Na does not affect the vertical m...

Reduction and broadening of the 1s..-->..2..pi..( resonance and the CO bond lengthening in the presence of Na signifies substantially increased metal to CO backbonding. |
