INFRA-ART FTIR Spectral Data Collection – Reference Materials

INFRA-ART FTIR Spectral Data Collection – Reference Materials is a curated reference dataset of ATR-FTIR spectra of materials relevant to cultural heritage research and conservation. The collection forms part of the INFRA-ART Spectral Library and provides a versioned release of its FTIR reference collection at the time of deposition. The dataset comprises 1,085 spectral records acquired from commercially available reference materials, including pigments, artists’ paints, binders, resins, waxes, and other materials commonly encountered in works of art, archaeological artefacts, and other cultural heritage objects. For each reference material, the dataset provides the raw FTIR spectrum in JCAMP-DX (.dx) format and the corresponding baseline-corrected spectrum in ASCII (.asc) format. Spectral files are accompanied by structured sample-level descriptive metadata and a metadata dictionary defining the fields used in the collection. A unique SampleID links the spectral files to their metadata and to the corresponding records in the INFRA-ART Spectral Library. The collection is intended to support spectral comparison and matching, material identification, analytical interpretation, method development, computational and data-driven analysis, and education and training in spectral interpretation and materials characterization. This Zenodo deposit provides a persistent and citable version of the collection for bulk access and reuse. The INFRA-ART Spectral Library is a dynamic database; subsequent versions of this dataset may therefore incorporate additions, corrections, and metadata enhancements as the underlying collection develops.
