The Fourier-transform infrared spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas. An FTIR spectrometer simultaneously collects high-resolution spectral data over a wide spectral range. The spectra data can be used to detect the molecular composition of the materials.

Case Studies
The “Hypogeum of the Garlands” is a sepulchral site, recently found in Grottaferrata (Lazio, Italy),
dating back to the first-second century AD.
A combination of spectroscopic techniques, including inelastic neutron scattering and Raman spectroscopy, and Fourier transform infrared spectroscopy, were applied to the analysis of these bone samples to give information about ancient Roman funerary practices.
