This dataset corresponds to a spectral database of geological, experimental and archaeological materials acquired by Fourier Transform Infrared Spectrometry in Attenuated Total Reflection mode (FTIR-ATR). The samples come mainly from the collections of the Muséum National d'Histoire Naturelle (Paris) or from specimens analysed on the "Plateforme de spectroscopie infrarouge du Muséum".These are mainly spectra of minerals (generally pure), archaeological and experimental samples, and organic compounds (natural or synthetic) that can be found in archaeological contexts. The main part of the spectral database has been acquired over mid/far infrared spectral range (4000 - 80 cm-1). Infrared spectra of some minerals are accompanied by corresponding X-ray diffractograms.
This dataset contains :- a table with information on the samples analysed and the conditions of analysis- FTIR-ATR spectra of these samples (Bruker OPUS files and JCAM-DX file). The spectra are classified according to the type of sample: archaeological (ARCH folder), experimental (EXP folder), miscellaneous geological (GEOL folder), mineral (MIN folder) and organic (ORG folder).- raw diffractograms (.xy ascii free format) and indexed diffractograms (pdf file)
