Abstract
In this work we have done a study of RAMAN spectroscopy on glycine sodium nitrate crystals. This study was supported with the respective X-ray diffraction and second-harmonic generation signal detection. The goal of this work is to modify the charge of glycine sodium nitrate in order to obtain three electric behaviors (Zwitterionic, Cationic, and Anionic) and perform the vibrational study on the characteristic peaks that appear in RAMAN spectra. Furthermore, with the change on the charge of the amino acid it is observed how it modifies the optical properties in the glycine sodium nitrate complex. Key words: RAMAN, glycine sodium nitrate (GSN), nonlinear optical (NLO), second-harmonic generation (SHG), pKa.
