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

Table 2

Chemical and material classes of the 125 nonexplosive chemicals and materials that are amongst the species that were tested. For the pure chemicals, species with multiple functional groups were tabulated in each class.
