uv photoemission results using filtered $h\ensuremath{\nu}=40.8$-eV radiation show strong shifts in the low-lying $\mathrm{C}(2s)$-derived levels of chemisorbed hydrocarbons on Ni relative to the higher-lying $\ensuremath{\sigma}$ levels. These differential shifts provide evidence for initial-state potential and/or rehybridization effects which are important in interpreting high-lying valence orbital shifts and the bonding of chemisorbed species.
