Linear dichroism electron scattering from chiral surfaces

The adsorption of R-phenylglycine on Cu(110) surfaces shows that the period ic superstructure of the chiral overlayer destroys the substrate mirror pla ne symmetry. Here, we report on the novel linear dichroism electron scatter ing method to determine the chirality, based on the unique symmetry of the chiral surface. The details of the molecular structure, with the absolute s urface chirality, are derived from the azimuthal variation of intensity of individual vibrational modes. (C) 2001 Elsevier Science B.V.
