Demonstrated Wavelength Portability of Raman Reference Data for Explosives and Chemical Detection

Table 1

Summary of the 20 explosives measured by both the 785 and 1064 nm Raman systems. In several cases the materials are named by their primary chemical component(s), followed by the common or commercial name, since the primary components define the spectrum. AN: ammonium nitrate, EGDN: ethylene glycol dinitrate, PETN: Pentaerythritol tetranitrate, NC: nitrocellulose, NG: nitroglycerine.
