An overview of Principal Components Analysis approaches in Raman studies of cultural heritage materials

open access: yesJournal of Raman Spectroscopy, Volume 55, Issue 2, Page 125-147, February 2024.
The present overview answers the need of evaluating the current state of the art concerning the application of principal components analysis (PCA) to Raman spectroscopy studies of cultural heritage materials. Painting materials, both colouring and binding ones, were considered, together with natural and synthetic glasses, biogenic and mineral ...
