Possibility of using Raman spectroscopy for studies of pastes of ballpoint pens

Raman spectroscopy (RS) is an important forensic tool. RS is a non-destructive method that does not require special preparation of the sample. This article shows the use of the method of determining the green ballpoint pen paste as a possibility of using Raman spectroscopy for the analysis of ballpoint pen pastes. The RS method provides additional information about the molecular and elemental composition of the ink. To this end, the samples for the study were prepared, which were coated with green ballpoint pen paste, which were analyzed by Raman spectroscopy. It was found that the use of Raman spectroscopy is possible to study the ink and that it is absolutely not a damaging method.
