THIN-LAYER ELECTROCHEMICAL CELL FOR INFRARED SPECTROSCOPIC MEASUREMENTS OF THE ELECTRODE/ELECTROLYTE INTERFACE.
Abstract
A thin-layer electrochemical cell which allows for the convenient measurement of infrared reflection-absorption spectra (IRRAS) of the electrode/electrolyte interphase has been designed and built. The use of this cell in a Fourier transform infrared reflection-absorption spectrometer utilizing polarization modulation is described. The IRRAS spectra obtained from this cell have been analyzed with the use of the generalized Fresnel equations for stratified media. Some of the computational results for the water-silver electrode interphase are used to interpret the measured spectra of water near the electrode.
