WebbResults are presented on explosives, pharmaceuticals, and common elements that show strong THz-Raman spectra, leading to clear discrimination of polymorphs, and improved sensitivity and reliability for chemical identification. All SPIE websites will be down for planned maintenance on 11 May, 2024. Webb(THz-Raman systems also capture the “fingerprint” region from 200cm-1 to >2,000cm-1). The low-frequency regions (for both Stokes and anti-Stokes shifts) are particularly difficult to resolve, as they reside extremely close to the Rayleigh excitation wavelength, which needs to be attenuated by at least OD 8 ...
