Simulation of SNIFTIRS experiments

We present a simulation of subtractively normalized interfacial Fourier tra nsform infrared spectra (SNIFTIRS) for the case of pyridine adsorbed at the Au(111) electrode. From experimental data and SNIFTIRS simulation the tilt angles can be evaluated as a function of the electrode potential for pyrid ine molecules adsorbed on terrace and defect sites, providing a detailed vi ew of the site and potential dependent molecular orientation.
