Identification of age markers from the structural features of Baltic amber using SERS

The paper describes the results of Raman spectroscopy and SERS for the study of fluorescent components of Baltic amber via the extraction method. Using SERS, it was possible to confirm in amber: tetracene and benzanthracene and others components. It has been shown that SERS methods are effective for the detection of aromatic and non-aromatic compounds. SERS be used to distinguish between different types of amber and isolate the necessary amber components. The obtained results are promising for compiling spectral maps of ambers for their possible classification by their place of origin and age.
