Abstract :
The geometry of the adsorption of pyridine on gold single-crystal electrode has been investigated by in situ difference frequency generation (DFG) in aromatic ring spectral range, by using the CLIO free electron laser. We found that pyridine adsorbs in an end-on configuration, via the nitrogen lone pair, the molecular plane being tilted. The potential dependence of the vibrational modes showed evidences of a reorientation of the molecule around the potential of zero charge.
