Forensic Science Applications of Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS): V. Direct Analysis of Metallic Paints—Screening of Panels

摘要: Direct sampling using diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) is particularly useful for rapidly screening metallic reference panels in some hit-and-run cases. For with finishes having high densities of flakes, spectra identical to those obtained conventional transmittance techniques may be DRIFTS and relatively minor spectral features used distinguish between different topcoats. low information about the constitutents topcoat presence specific pigments undercoats also certain These data, likewise, serve differentiate finish systems.
