Abstract
The problem of identification of ozone-depleting substances was formulated because of challenges in the field of climatological research. Based on the data on controlled ozone-depleting substances and greenhouse gases, a description of refrigerants subjected to accounting during transportation and storage on the territory of the Russian Federation was given. A comparative analysis of methods, including chromatography-mass spectrometry, infrared absorption spectroscopy, and Raman spectroscopy for determining the composition of refrigerants by precision and time parameters is presented. The choice of the Raman spectroscopy method for the identification of complex-component compounds is substantiated. An example of R-12 refrigerant identification based on calculating spectra of vibrational processes of bonds in a molecule is considered and compared with recording spectral data. Based on the structure of the R-12 refrigerant molecule, the spectral lines were calculated depending on molecular vibrations. The lines identified were recorded in the Raman spectrum of the refrigerant detected by an experimental setup for the identification of ozone-depleting substances. It was concluded that the Raman method is promising for identification of multicomponent refrigerants.

Keywords: refrigerants, ozone-depleting substances, freons, analytical systems, Raman spectroscopy, chromatography-mass spectrometry, infrared absorption spectroscopy.
