摘　　要：本文测量了甲基橙分子(MO)的正常拉曼光谱(NRS)和其吸附在银纳米颗粒上的表面增强拉曼光谱(SERS),同时又运用了高斯98软件计算了甲基橙分子的拉曼光谱。理论计算结果很好地符合了实验测量结果。最后,对甲基橙分子在银纳米粒子表面上的可能吸附状态进行了讨论。The Normal Raman spectrum（NRS） of methyl orange（MO） was observed in this paper and presents theoretical vibrational spectra calculated from a Gauss 98 software on the basis of B3 LYP with 6-31 basis set. The calculated results show very good agreement with the experimen-tally observed Raman frequencies. We also report the surface enhanced Raman spectrum（SERS） of MO adsorbed on silver nanoparticles surface. Finally, the possible adsorbed state of MO on the silver nanoparticles surface is discussed.
