Raman Vibrational Study of Pigments With Patrimonial Interest for the Chilean Cultural Heritage

Abstract: Seven pigments of patrimonial interest for the Chilean artwork were analyzed by means of Raman spectroscopy by using the 632.8 nm excitation laser line. Samples were supplied by the National Center of Conservation and Restoration of Chile (CNCR) in a cooperative effort to determine the exact molecular composition of each pigment. In this contribution we propose to settle the use of the Raman spectroscopy as a method to contribute to the conservation and/or restoration procedures, and thus to the authentication… Show more

“…In IR, the most intense bands are at 470, 730, 749, 827, 876, 933, 1301, 1355, 1388, 1445, 1506, and 1591 cm −1 . This set of bands is closely related to a copper phthalocyanine complex following published data,11, 44–46 but they could not be fully ascribed to that specific pigment.…”

“…die maximale farbliche Veränderung der Pigmente an (Bild 5). Zur Analyse der chemischen Veränderungen auf molekularer Ebene wurde die sogenannte Ramanspektroskopie 1 herangezogen (Bild 6) [7,8]. In der Kunstwerktechnologie wird diese Analysemethode üblicherweise zur Identifizierung von anorganischen Pigmenten in Kunstobjekten eingesetzt, da sie in-situ und zerstörungsfrei angewendet werden kann.…”

“…A identificação de corantes e pigmentos por espectroscopia Raman é um procedimento que vem se tornando rotineiro em investigações de bens culturais e é o tópico mais recorrente nos estudos empregando a técnica, inclusive na América do Sul (DE OLIVEIRA et al, 1998;DE LA FUENTE e MARTINEZ, 2008;AGUAYO et al, 2010;DARCHUK et al, 2010;DE FARIA e PUGLIERI, 2011;DE FARIA et al, 2011;ACEVEDO et al, 2012;BUGLIANI et al, 2012;CENTENO et al, 2012;HALAC et al, 2012;MARTE et al, 2012;MORETTI et al, 2013;TOMASINI et al, 2013;MARTE et al, 2014;OGALDE et al, 2014;ACEVEDO et al, 2015;OGALDE et al, 2015;SEPULVEDA et al, 2015;DE FARIA e PUGLIERI, 2016;FREIRE et al, 2016;TOMASINI et al, 2016). Algumas publicações que não envolvem bens culturais sul americanos, mas que resultaram de análises realizadas no Brasil também podem ser citados, como é o caso de pigmentos egípcios antigos (DAVID et al, 2001;EDWARDS et al, 2004) e de pigmentos em pinturas murais romano-britânicas na região de Northamptonshire, Reino Unido (EDWARDS et al, 2003 , v. XV, n.30., p. 344-365 A corrosão de objetos feitos em metal também é tema de interesse, em especial no contexto da conservação preventiva.…”
