Abstract
Identification of paint traces by FTIR spectroscopy is a recognized forensic method. It is especially important in a hit and run car accidents. The objective was to discover how automotive paints exposed to UV light are affected. Methods we used were FTIR spectroscopy and polarised microscopy. Our primary results were IR spectra of 13 samples. We used samples from a few manufacturers in yellow, red, blue and green colour. Spray paints were applied on stainless steel and left under UVB (UV light with a wavelength of 304 nm) and UVC (UV light with a wavelength of 254 nm) for 30 days. We obtained IR spectra of samples after 15 and 30 days. We concluded that samples visibly changed after the experiment. We saw some interesting modifications of IR spectra, which could give us an information of what is happening in car paint sample when exposed to UV light.
Abstract (croatian)
Identifikacija tragova boja s pomoću FTIR spektroskopije je poznata forenzična metoda koja se koristi pri ispitivanjima automobilskih nesreća. Cilj je bio saznati kako se mijenjaju automobilske boje izložene UV svjetlu. Metode koje smo koristili bile su FTIR spektroskopija i analiza s polarizirajućim mikroskopom. Naši primarni rezultati bili su IR spektri 13 uzoraka. Koristili smo uzorke nekoliko proizvođača u žutoj, crvenoj, plavoj i zelenoj boji. Boje za raspršivanje nanesene su na pločice od nehrđajućeg čelika i ostavljene pod UVB (UV svjetlo s valnom duljinom od 304 nm) i UVC (UV svjetlo s valnom duljinom od 254 nm) tijekom 30 dana. Nakon 15 i 30 dana dobili smo IR spektre uzoraka. Ustanovili smo da su se uzorci vidno izmijenjili nakon eksperimenta. U IR spektrima smo primjetili promjene inteziteta te pojavu i nestanak pojedinih vrpci kod boja koje su bile izložene UV svijetlu u odnosu na referentne uzorke. Ti podaci bi nam mogli dati informacije o tome što se događa u uzorku automobilske boje kada je izložena UV svjetlu.
