Description
Complete text of publication follows. The present study follows the changes of gamma irradiated historic pigments and experimental models of oil paintings with non-destructive and non-contact spectroscopic analytical techniques which are the only ones accepted by the conservators/restorers community. Molecular structure characterization was performed by FT-IR / Raman spectroscopy using a Bruker Vertex 70 class equipped with two mobile probes: a MIR fibre module for MIR probes (with LN2 cooled detector) and a Raman RAM II module (LN2 Ge detector) with a RAMPROBE fibre. Colour was measured by a portable reflectance spectrophotometer (Miniscan XE Plus, HunterLab) in diffuse/8 deg geometry with a beam diameter of 4 mm and specular component included. Correlations between colour shifts and changes in molecular structure induced by gamma irradiation were further investigated.
