Detection of Surface Chirality by Electrolyte Electroreflectance Rotational Anisotropy

The ability of electrolyte electroreflectance rotational anisotropy (EERRA) to detect surface chirality is demonstrated by measuring the EERRA of Au(11 7 5) L and Au(11 7 5) D . Chiral surfaces do not contain any symmetry planes, and, hence, in their case χ xy ≠ χ yx . Accordingly, the EERRA patterns, like the surfaces they originate from, do not contain any symmetry planes, and are, hence, chiral, the pattern corresponding to Au(11 7 5) L being the mirror image of the pattern corresponding to Au(11 7 5) D .
