Modulated Surface Vibrational Spectroscopies at Electrode/Electrolyte Interfaces.
Abstract
In this report, we will discuss the applicability of a new infrared vibrational probe to studies of the structure and orientations of molecular species at or near the electrode-solution interface and the dynamics of adsorption/desorption processes. Such studies have been virtually impossible with available instrumentation in the past due to the extremely large absorbance by the solvent/electrolyte system. Early investigations on electrochemical systems were thus attempted primarily with internal reflectance methods that did not require that the radiation pass through the bulk solvent/electrolyte system. This method is limited, however, due to the few choices of infrared-transport electrode materials (semiconducting materials or very thin metal films on insulating transparent salts and polymers) in addition to more stringent cell designs and electrode geometries.
