摘要：

In situ Fourier transform reflection absorption infrared spectroscopy has been employed as a probe of the local pH in the thin layer of electrolyte solution trapped between the electrode and the optical window. The method is based on the differences in the spectral properties of certain bases and their conjugated acids, which makes it possible to determine pH changes on the basis of the relative Integrated intensities of the two species. Illustrations are given for the carbonate/bicarbonate and acetate/acetic acid systems and the oxidation of CO in alkaline media. © 1990, American Chemical Society. All rights reserved.
