✦ Synopsis

Angle-resolved photoemission experiments using synchrotron radiation reveal a reduction from C& to C3v,av in the local symmetry of benzene on Rh( 11 I ) in the presence of coadsorbed Na. This is interpreted via a model of the coadsorbate layer in which the benzene molecules, adsorbed on-top in a pure benzene layer, occupy threefold hollow positions with a possible out-of-plane C-H bending distortion. The benzene energetics are influenced only weakly by coadsorbed Na.
