Paint Data Query database

IR spectra also constitute the starting point for the research of vehicles involved in hit-and-run accidents databases are built containing IR information of every layer characterizing manufactured vehicles. Some important examples are the European Collection of Automotive Paints (EUCAP) Database and the FBI/RCMP Paint Data Query (PDQ) Automotive Paint Database. 

Analysis of paints is a routine part of forensic investigations of hit-and-run accidents or collisions involving vehicles. Paints have complex formulations. Automotive paints are applied in layers and the sequence and colours of the layers provide information on the origins of the vehicle. By matching IR and Raman spectroscopic data from a vehicle paint sample to those in databases (e.g. the European Collection of Automotive Paints and Paint Data Query), it is possible to determine the vehicle s manufacturer and year of production. The main components of a paint fall into four categories ...
