摘要

Commercial paracetamol drugs (normal and sinus) are analyzed using Raman and SERS spectroscopies. The active compound present in commercially tablets could be accurately identified and monitored even through the blister pack. Raman spectra show that the normal paracetamol contains a mixture between the monoclinic and orthorhombic forms, while the sinus paracetamol contains just the monoclinic form. The SERS spectra of paracetamol on Ag island films of different roughnesses have been obtained and discussed. From the SERS spectra it was concluded that the paracetamol molecules are chemisorbed on the Ag-surface in a flat orientation through the lone pair electrons of the nitrogen atom and the π electrons of the aromatic ring.
