Abstract

The solution of the problem of identification of amber (succinite) on the example of natural polymer material of organic origin on the basis of its infrared absorption spectra is proposed. Taking into account the growing demand for the use of such composite materials on an industrial scale and the insufficiency of existing methods for determining their composition, the proposed method can become a new solution to the problem of identification. The basis of the proposed method for the study of succinite using infrared spectroscopy is translucent spectroscopy, with the measurement of mirror and diffuse reflection. The samples amber of the Palmniken Deposit obtained in the city of Kaliningrad of the Russian Federation were used as the objects studied. The data of infrared spectra of succinite obtained by the proposed method of infrared spectroscopy are obtained and presented in comparison. Five main links on the obtained infrared spectra have been experimentally determined, which can be used as characteristic features for identification and diagnostics of succinite by the material composition. The proposed method may be of interest in the theory of knowledge of material science, research related to the processes of identification, processing of production of amber.

Highlights

More than 100 types of fossil resins have been observed in the world, but their degree of study with the help of IR spectroscopy is insufficient
This gap in research dictates the purpose of this paper: the use of IR spectroscopy to study the optical properties of inhomogeneous polymer materials of organic origin with anisotropic physical and mechanical characteristics on the example of amber
If we combine the work on the classification of amber materials, to enrich them with experimental data of IR spectra of structural and material composition, the basis for identification of nuclear materials based on infrared spectroscopy can be obtained

Summary

Introduction

Today a number of domestic well-known [1,2,3] and abroad [4,5] scientific works, devoted to the study of the optical properties of amber They consider the methods of infrared (IR) spectroscopy on samples of both treated and untreated amber deposits in Bulgaria and Poland. More than 100 types of fossil resins have been observed in the world, but their degree of study with the help of IR spectroscopy is insufficient This is confirmed by a large number of works on the study of samples of materials from various fields presented only in a generalized form, without a detailed description of the obtained characteristics of IR spectra [6,7,8,9,10,11,12,13]. Spectral analysis in the infrared range is one of the universal methods of obtaining maximum complete information of the material and structural composition of the materials under study, which is necessary for scientifically based, complete and objective evaluation
