## Abstract The laser excitation wavelength is an important parameter in obtaining definitive Raman spectra from pharmaceutical drug substances. This paper investigates the effect of changing wavelength on the Raman spectra of four different drug substances: paracetamol, paroxetine and ranitidine (
The e β ect of di β erent polarization orientations of the excitation source on the Raman and photoluminescence (PL) spectra of a porous silicon (PS) layer within two di β erent micro-regions was investigated. Two micro-regions (2 lm) along the (100) direction were studied, close to the crystalline sil
