The normal Raman spectrum and surface enhanced Raman spectrum(SERS)in silver nanomaterial of pseudo ephedrine were studied in this article.Geometry structure and theoretical Raman spectrum of pseudo e-phedrine were studied by density functional theory method using B3LYP/6-311G + +(d,p),and the vibra-tional modes were assigned comprehensively by software of Gauss view.The silver cluster nanomaterial substrate was fabricated by self-assembling and achieved good enhancement effect in SERS of pseudo ephedrine.The re-sults showed that the theoretically calculated spectrum of pseudo ephedrine was consistent with the experimental spectrum.Theoretical calculation provided significant basis for assigning the vibrational peaks.The molecule was absorbed on the silver surface,and the benzene ring was perpendicular to the surface.The study provides a strong theoretical basis for the spectroscopy research of pseudo ephedrine,also supplies important reference for the spectroscopy research of amphetamine drugs.
