Abstract. The work reflects the principles of Raman spectroscopy, its advantages and application in forensic examination of materials, substances and products. Some developments in the modernization of this method and the possibility of using Raman spectroscopy in other areas of forensic examination are presented. These studies demonstrate the wide applicability of Raman spectroscopy in forensic uses and, more importantly, in the use of portable and handheld devices. Besides, Raman spectroscopy finds extensive use in the examination of drugs, psychotropic substances, polymeric materials, fibrous materials, explosive substances, etc. However, additional efforts are needed for the development of this method. One of the most important steps in this process should be to develop and test spectral libraries. The use of Raman spectroscopy as a versatile analytical tool in forensic science is constantly evolving. Despite the wide range of possibilities, Raman spectroscopy is faced with problems such as fluorescence interference, low sensitivity. Raman spectroscopy is one of the few methods that can quickly provide accurate desired information in the analysis of substances, while not damaging the sample.
Key words: spectroscopy; combination scattering spectroscopy; Raman spectroscopy; analysis methods; forensic examination of materials, substances and products
