1974年英国Fleischmann等人发表文章,报告了吸附在银电极(研究电极)表面的吡啶单分子层的拉曼光谱,他们注意到这个拉曼光谱的波数有一些位移,而且某些拉曼谱带随着加在银电极上电位的变化而有所改变(图1)。但他们并没有感到有什么异常,实际上这个实验开创了拉曼散射研究的新局面。 In 1974, an article published by Fleischmann et al. Reported Raman spectra of pyridine monolayers adsorbed on the surface of silver electrodes (research electrodes). They noticed that there was some shift in the wavenumber of this Raman spectrum, and some Raman bands With the addition of silver electrode potential changes have changed (Figure 1). But they did not feel anything unusual, in fact, this experiment created a new situation in Raman scattering research.
