In the field of FTIR spectroscopy of heritage materials, the Far Infrared (FIR) region has been less investigated than the Mid Infrared (MIR) although it has some advantages, particularly in characterisation of inorganic compounds such as painting

Furthermore, FIR spectroscopy is a complementary technique to Raman spectroscopy in particular in the presence of fluorescence. In this study we have investigated the FIR region (600-90 cm-1) of eight inorganic standard pigments employed in art. The eight standard compounds are the preliminary results collected in order to build a larger FIR-database library. One case study is also presented.
