摘　　要：本文首次报道了茄尼醇分子的常规拉曼光谱 (RRS)及该分子在铂电极上的表面增强拉曼散射(SERS)谱 ,并对它的谱带进行了初步指认。从其常规拉曼光谱和SERS谱的对比和分析推断 ,茄尼醇分子是通过CC等键吸附在铂电极表面的。这种分子RRS和SERS谱的明显差异表明 ,该分子与铂电极表面发生了强的相互作用。这种相互作用对吸附在铂电极上的茄尼醇分子结构发生了很大的扰动。The normal Raman spectrum (RRS) of solanesol molecules and surface enhanced raman scattering (SERS) of these mdecules adsorbted on Pt electrode surface are reported in this paper. By comparising that the results show that the molecules of solanesol is adsorbted on the Pt surface through the C = C bond. The large difference between RRS and SERS demonstrates that the interaction between the molecules and Pt surface is rather strong and this interaction leads to a large disturbance to the molecules structure of solanesol.
