Abstract
The Raman spectra of amber (succinite) of different transparency levels of the Palmniken Deposit of Kaliningrad of Russia were obtained using the Fourier Transform–Raman spectroscopy method, which allows obtaining real and elemental compositions. It was found that succinite (amber) is an organic unsaturated carbon - chain homopolymer with different valence oscillations of aliphatic CH2 and CH3 groups, containing heteroatoms C=C and CH in the main chain with valence in RNS=CH2 and deformation in trans RHC=CHR' oscillations with chemical side chains of up to 8 subgroups. Three main connections were experimentally identified on the obtained Raman spectra, which can be used as characteristic features for identification and diagnostics of succinite of the Palmniken Deposit. Practical significance. The proposed method may be of interest for chemistry, materials science and research related to identification processes. The performed research can be used in the synthesis of high-molecular compounds, in issues related to the development and distribution of various applications of organic materials.
Highlights
In modern materials science, polymers are studied due to their wide use as materials with special optical, physical and mechanical properties [1,2]
Polymer materials are economically and technologically promising as optical communication components, since in the near future, modern thin and expensive optical fibers, as well as those made with glass or quartz, will be replaced with less expensive materials [3]
Three main bonds were identified on the obtained Raman spectra, which can be used as characteristic features for identifying and diagnosing succinate
Summary
Polymers are studied due to their wide use as materials with special optical, physical and mechanical properties [1,2]. The stage of studying polymer materials is to solve the problem of mechanical and chemical resistance and stability in the interaction of devices with the environment [8]. The choice of materials that have the above properties simultaneously allows you to adapt the optical or mechanical parameters in the process of polymer synthesis [9,10]. In this context, it is important to study and understand the structure of natural polymer materials, in particular amber, which shows very interesting characteristics in terms of optical properties, namely fluorescence, birefringence, transparency in UV radiation in combination with mechanical and chemical resistance [11,12]
