Abstract: SERS of N-(1-(2-chlorophenyl)-2-(4-nitrophenyl)ethyl)-4- methylbenzenesulfonamide (CNPSA) by Ag NPs was investigated using Raman spectroscopy. Ag NPs were synthesized by solution combustion method using citric acid as fuels. The prepared Ag NPs were characterized by XRD, UV, HR-TEM, FESEM and SERS studies. The prepared Ag NPs exhibit cubic crystalline structure with grain size 46nm. The surface plasmon resonance peak was found at 380nm. The spherical shape of Ag NPs was confirmed by FESEM and HR-TEM. The orientation of CNPSA molecule on Ag NPs has been inferred from nRs and SERS spectral feature. The molecule is adsorbed on the Ag NPs with the benzene ring in a tilted orientation. The presence of amino and sulfate group vibrations in the SERS spectrum reveal the interaction between amino and sulfate. newline
