Scientists of the IKBFU Research Centre “Fundamental and Applied Photonics. Nanophotonics” date amber using an original method based on Raman spectroscopy.
The researchers assumed that each specimen has a unique molecular structure the features of which change with age. Using optical sensors, the physicists were able to estimate the chemical composition of the amber and the relative age of the fossilised resins.
Experts examined 57 samples from Russia, the USA, the Dominican Republic, Germany, Ukraine, New Zealand, Mexico and France, including the amber from the age of dinosaurs (Triassic period, ca. 200–220 million years old).
