Abstract
New experiments and more powerful theoretical analysis provide an accurate determination of geometry for the c(2 × 2)CO/Cu(001) and Ni(001) structures. The new CO bond length is 1.15 Å and the molecule is essentially vertical in both cases, resolving an earlier discrepancy with photoemission data. New theoretical methods for handling molecules at surfaces are described which can be extended to molecules much larger than CO. Some discussion of thermal vibrations is made.Keywords
