The IR and Raman spectra of alizarin, purpurin, kermesic acid, and carminic acid have been computed performing density functional theory calculations at the B3LYP/6‐31G(d) level of theory. The computational approach adopted has been validated on the basis of a series of calculations with different level of theory on the anthraquinone molecule, the common moiety of these dyes. The computed vibrational...
In the present work, we focus on the assessment of the chemical and physical side effects induced by UV laser ablation of varnish samples (i.e. mastic, oil-mastic, dammar, and bleached shellac) after natural curing and artificial ageing using micro-Raman spectroscopy, laser-induced fluorescence and environmental scanning electron microscopy. The varnish films were irradiated with the fifth (213nm)...
