Simulation of SNIFTIRS experiments

We present a simulation of subtractively normalized interfacial Fourier transform 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 pyridine molecules adsorbed on terrace and defect sites, providing a detailed view of the site and potential dependent molecular orientation.
