Fourier Transform Infrared Spectroscopy is a molecular spectroscopy which is used to characterize both organic and inorganic evidence.  Its uses range from differentiation of toner samples, which indicates the use of multiple xerographic machines, to the detection of specific inorganic components in paper or pencil, which would aid in the determination of common origin.
