The method of identification of substances by the position of individual characteristic lines in the Raman spectra

Abstract

The task of identifying substances is relevant in many areas of research related to quality control and safety of safety materials. Rapid identification and analysis of substances by sampling-free methods can be used to solve problems of drug distribution and prevent terrorist acts. Raman spectroscopy is widely used for these purposes. The analysis of substances can be performed using mathematical methods for comparing the obtained spectra and spectra from the database. Since the basic information about the structure of the molecules of a substance is reflected in the spectral lines of the raman, it is advisable to use them when analyzing the spectra. The entire raman spectra are usually used for the identification task, but this is associated with a number of disadvantages, such as the difficulty of replenishing the database and the inability to use data that is publicly available. Taking into account the above, a method for identifying the substance is proposed.
