Surface structures of {radical}3 {times} {radical}3 R30{degrees} Cl/Ni(111) and c(2 {times} 2)Cl/Cu(001) were determined using low- temperature angle-resolved photoemission extended fine structure (ARPEFS), which yields both more accurate surface and near-surface structural information for deeper substrate layers. A study of surface-atom vibrations for {radical}3 {times} {radical}3 R30{degrees} Cl/Ni(111) and c(2 {times} 2)Cl/Cu(001) was made using temperature-dependent ARPEFS. A model for predicting the adsorbate vibrational anisotropy from surface structures was proposed and also successfully applied to several adsorbate systems. This model offered a simple and straightforward physical picture for understanding different types of vibrational anisotropy.
