摘　　要：针对邻羟基苯甲酸(OHBA)在银胶溶液和覆银滤纸上的吸附方式,建立了一个理论模型,经过理论值和实验值对比,发现该模型比较合理。Surface-enhanced Raman scattering（ SERS） spectra of o-hydroxybenzoic acid（ OHBA） in the silver colloidal solution and on the dried silver-coated filter paper are measured,respectively. A model of OHBA adsorbed on the surfaces of silver substrate is established and the Raman spectra of the model using DFT-B3PW91 with lanl2 dz is calculated. By comparing the theoretical values with the experimental values,we find that the calculated Raman frequencies of the model are in good agreement with experimental values,respectively.
