Abstract
The concentration dependence of proton Knight shifts associated with c hemisorbed hydrogen on Ru-Cu bimetallics has been studied in terms of conduction electron polarization and surface segregation. Comparison o f the calculated results with the experimental results suggests that t he proton Knight shift for Ru-Cu particles results mainly from the hyd rogen atoms experiencing a hyperfine interaction with three Ru first n earest neighbors.
