自七十年代中期,吸附在银电极表面上的吡啶的表面增强拉曼散射效应被发现以来,大量的有关表面增强拉曼散射效应的研究集中在含氮有机化合物上.对含硫化合物,尤其是对含硫和氮的杂环化合物的研究较少.在六十年代中期,Califano,Sbrana 和Davidovics 等人及其合作者分别研究了噻唑和异噻唑的红外和拉曼谱.本文研究了含巯基化合物,即系列的苯骈噻唑类化合物的普通拉曼谱(NRS)及其吸附在银电极表面上所产生的表面增强拉曼谱(SERS),并讨论了噻唑杂环上不同取代基对谱图的影响.
Since the mid-1970s, the surface-enhanced Raman scattering effect of pyridine adsorbed on the silver electrode surface has been extensively studied, a large number of studies on the surface-enhanced Raman scattering effect have been focused on nitrogen-containing organic compounds. Is less studied on sulfur and nitrogen-containing heterocyclic compounds.In the mid-1960s, Califano, Sbrana and Davidovics et al and their collaborators studied the infrared and Raman spectra of thiazoles and isothiazoles respectively.In this paper, The common Raman spectrum (NRS) of the thiol compounds, namely the series of benzothiazole compounds, and the surface enhanced Raman spectra (SERS) of their adsorption on the silver electrode surface were discussed. The effects of different substituents on the thiazole heterocycles Effect of spectrum.
