In the field of FTIR spectroscopy, the Far Infrared (FIR) region is less investigated than the Mid Infrared (MIR) but it presents some advantages, when characterising inorganic compounds such as painting materials and corrosion products, which are not active in the MIR. Furthermore FIR spectroscopy is a complementary technique to Raman spectroscopy in particular in the presence of fluorescence. In these experiments 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.

Abstract
In the field of FTIR spectroscopy, the Far Infrared (FIR) region is less investigated than the Mid Infrared (MIR) but it presents some advantages, when characterising inorganic compounds such as painting materials and corrosion products, which are not active in the MIR. Furthermore FIR spectroscopy is a complementary technique to Raman spectroscopy in particular in the presence of fluorescence. In these experiments 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
