Abstract

Relations between surface force constants and bond lengths are discussed for two surfaces. First, on the oxygen-covered Cu(100) surface, we have obtained the force constants of the O-Cu bonds based on lattice dynamical analysis. The results are consistent with those for the chemisorption site of oxygen atoms in the missing row model proposed by Zeng et al. [Surf. Sci. 208 (1989) L7] using LEED intensity analysis. Concerning the relative position of the oxygen atoms against the topmost Cu atoms, however, there is a small difference between these two results. Second, the surface force constants of the B-B bonds in the LaB6(100) surface suggest the deformation of the three-dimensional network of boron at the surface, for which no data have been reported so far.
