Abstract
The authors have analyzed the spin-lattice relaxation of CO chemisorbed on supported Pt particles. They fit their relaxation data with a minimum set of relaxation times () ranging from 0.009 to 6 s at 77 K. They find that each component is inversely proportional to the temperature, but that some components do not satisfy the Korringa relationship. They express the relaxation by conduction electrons in terms of tight-binding coefficients and evaluate the amount of mixing of the CO orbitals with the Pt conduction bands to account for the observed . They also analyze data for CO on Ir and Pd.
