Pollutant identification on the walls of “Valence Aqueduct” (Aqueduct of Valens, Istanbul) by portable handheld Raman, SEM-EDX, Far-infrared and Mid-infrared techniques, TURCMOS 2013- International Turkish Congress on Molecular Spectroscopy Özet Kitabı, Sf.100, 15-20 September 2013

This study represents the first Far infrared, Mid infrared, Raman spectroscopic and SEM-EDX studies of the pollutants from the walls of Valence Aqueduct (Aqueduct of Valens), Istanbul, Turkey. Provided that enough amount of sample is available, Far infrared spectroscopy is a useful analytical method particularly in characterisation of inorganic compounds such as painting materials and corrosion products, which are not active in the mid-infrared. Furthermore, far-infrared spectroscopy is a complementary technique to Raman spectroscopy in particular in the presence of fluorescence.
