Infrared Reflection-Adsorption Spectroscopy of the Electrode/Electrolyte Solution Interface: Optical Considerations

Abstract

Calculations based on the classical Fresnel equations have been carried out to investigate the effect of various experimental parameters on infrared spectra obtained for molecules adsorbed at the electrode/solution interface. The effects considered include the nature of window material, variation in the angle of incidence, incident beam diameter, instrument focus, and the presence of an adsorbing bulk electrolyte solution. It is shown that under certain circumstances, the resultant spectra are enhanced with respect to those obtained in the absence of an infrared window and bulk adsorbing phase. The significance of the present results with respect to practical experiments is discussed. Keywords: Electrochemistry, Physical optics, Reflection spectroscopy, EMIRS, SNIFTIRS, IRRAS.
