Coherent’s patented THz-Raman Spectroscopy Systems extend the range of traditional Raman spectroscopy into the terahertz/low-wave number, exploring the same range of energy transitions as terahertz spectroscopy – without limiting the ability to measure the fingerprint region.
The THz-Raman spectral region covers both Stokes and anti-Stokes signals from ±5 cm-1to 200 cm-1, (or 150 GHz to 6 THz), which contain important structural information about the molecule or crystal lattice. This region reveals a new “structural fingerprint” to complement the traditional chemical fingerprint of Raman, enabling simultaneous analysis of both molecular structure and chemical composition in one instrument for advanced materials characterization.
