摘要
A spectroelectrochemical cell designed for observing electrode surface and interfacial phenomena in conjunction with Raman spectroscopy is described. The many novel features of the cell allow experimental flexibility and ease of operation substantially above those of other cells. With this cell, the effect of laser illumination and excitation wavelength on the intensity of the Raman spectrum from pyridine adsorbed to silver as studied. The largest enhancements were found for electrochemically roughened silver with illumination of the surface by 8824-A light during the roughening. A model is proposed to explain the phenomenon.
