Spectral Libraries of Pigments Generated by Quantum Cascade Laser Infrared Microspectroscopy and Derivative Spectroscopy

This dataset contains three spectral libraries with infrared spectra of pigments. These spectra were measured using Quantum Cascade Laser Infrared Microspectroscopy and processed with first- and second-derivative spectroscopy. The spectral data are provided in CSV format, along with metadata, to enable reproducible analysis, spectral comparison, and pigment identification studies. These libraries are compatible with the open-source MIA (Multiscale Image Analysis) software by Hennes Rave (https://github.com/hennesrave/multiscale-image-analysis).
