Abstract:Terahertz spectroscopy has been increasingly utilized
as an effective
nondestructive tool for the diagnosis, analysis, and restoration of
artworks. In particular, in the case of artist’s pigments,
the terahertz probe reveals the vibrational modes that are unique
to a given pigment species under study, motivating the ongoing efforts
to establish a comprehensive terahertz spectral database of representative
pigments. Standard archived spectra are typically acquired at room
temperature and susceptible to spectral… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
