摘要：

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 zigzag chains with oxygen located in threefold-coordinated sites on an otherwise undistorted Rh(110) surface. Due to the strong interaction of oxygen with Rh the contraction of the first Rh interlayer spacing (observed for the clean surface) is globally removed. LEED investigations on the (2 x 2)pg-O structure prove the presence of a missing-row reconstruction of the Rh substrate.
