摘要
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.
2-mercaptobenzothiazole(2-HSBT)not only reacted with silver subcolloid andshowed enhancing effect of the surface Raman scattering,but also reacted with theroughened silver electrode.The normal Raman spectra(NRS)of benzothiazole compounds and their SERSadsorbed on the roughened silver electrode were investigated,the influences of thedifferent substituting groups on NRS and SERS were also discussed.
