Application of Fluorescence Line Narrowing Spectrosocopy to Forensic Fiber Examination

This objective of this award is to develop a nondestructive analytical methodology capable of providing highly discriminating identification of textile fibers encountered as physical evidence in criminal investigations. The applicant proposes to use fluorescence line narrowing spectroscopy, a high-resolution luminescence technique, to characterize textile dyestuffs for the purpose of establishing the possibility of a common source of a questioned and a known fiber.
