Popis:	Using FEM, work function measurements were carried out on kinked surface areas of Pt and Rh ({210}, {531}Rh, {321}, {520}, {310}, {320}, {430} and {741}Pt). The work function change after saturated CO adsorption at room temperature, ΔoCO, increases with decreasing work function of the corresponding clean adsorbent area, ok. The dependence appears to be linear. The slope was identified as the ratio of two surface dipole moments, μ CO μ Me . (μCO dipole moment (per molecule) of the CO adlayer adsorbed on kink atoms; μMe dipole moment of the metal kink atom.) The experimental values of the ratio are close to unity.
