ABSTRACT
The main purpose of this study is to detect di erent ecologically harmful substances in aqueous solutions using surface enhanced Raman spectroscopy (SERS) as a tool. Therefore, assigning the vibrational modes is essential to identify the substances. SERS using silver nanoparticles was used to obtain reproducible intense signals for detection of molecules in aqueous solutions. The study extends the use of thiol layers for attracting molecules onto the silver surface. Optimization for SERS measurements during scanning was made by scanning di erent points per line and different lines per image. The dependence of SERS intensity on scan speed had been demonstrated using descriptive gures. The spectra in pure solid forms and aqueous solutions of the carbamezapine (CBZ) sample helped for assigning which band belongs to which bond in the compound.
