Abstract

We present terahertz spectroscopy and analysis of commercially available quinacridone pigments in the 0-5 THz range. Our results show clear distinction between the β and γ crystalline phases responsible for the deep violet (β) to red (γ) colour pigments. We reveal a large number of absorptions in the terahertz regime shown to depend on the constituent phase as well as temperature.
