Abstract
A quantitative low-energy electron-diffraction (LEED) analysis of the Rh(110)-(2 x 1)pg-O structure revealed a model which consists of O zig zag chains with oxygen located in threefold-coordinated sites on an ot herwise undistorted Rh(110) surface. Due to the strong interaction of oxygen with Rh the contraction of the first Rh interlayer spacing (obs erved for the clean surface) is globally removed. LEED investigations on the (2 x 2)pg-O structure prove the presence of a missing-row recon struction of the Rh substrate.
