Terahertz Spectroscopy and Quantum Mechanical Simulations of Crystalline Copper-Containing Historical Pigments
Terahertz spectroscopy is a non-destructive analytical technique used in art conservation and restoration. It can provide compelling data concerning the composition and condition of culturally valuable and historical objects. Terahertz spectral databases of modern and ancient artists’ pigments exist, but lack explanations for the origins of the unique spectral features. This paper present terahertz spectra…
