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

Figure 4

Example of a successful identification for comparing the 785 nm data versus the 1064 nm library. The result is typical; for most species the 1064 nm spectrum of the same compound is identified as the top candidate “hit” for the 785 spectrum. Scores for the top three hits are at right. Spectra are scaled 0 to 2 and have been vertically offset for clarity.
