摘要
Reflection-absorbtion FTIR spectra were recorded for the interaction of cyclopropane with Ni(lll) and Cu(lll) surfaces. The very different spectra observed for the two systems permit a clear differentiation of the adsorption geometries adopted on both metals. Cyclopropane lies flat on Cu(lll), whereas the interaction with Ni(lll) is preferentially with one edge of the molecule. The bonding interactions at the origin of the observed geometries are discussed. (C) 1997 Elsevier Science B.V.
