FTIR spectra of enamel from African ungulates

Reference FTIR spectra of tooth enamel from African ungulate species for the assessment of carbonate hydroxyapatite crystallinity. Samples were analysed in transmission mode using a Thermo Scientific Nicolet iS5 infrared spectrometer equipped with an iD1 transmission module and a deuterated triglycine sulphate (DTGS) detector. Spectra were collected in the 4000-400 cm-1 spectral region at 4 cm-1 resolution and in 32 scans, and processed using OMNIC v. 9.13. Spectra are available in .spa and .csv formats. This library is part of the following publication: Toffolo, M. B., Richard, M., 2024. Infrared spectral library of tooth enamel from African ungulates for accurate electron spin resonance dating.
