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. (C) 2001 Else
