Researchers at the University of Tokyo have combined two current spectroscopy techniques — infrared (IR) absorption and Raman scattering spectrometry — to create complementary vibrational spectroscopy. The new technique employs IR absorption and Raman scattering spectroscopy simultaneously to allow researchers to measure the complete broadband vibrational spectra in the molecular fingerprint region with a single instrument. Advancements in ultrashort pulsed laser technology have made complementary vibrational spectroscopy possible, the Tokyo team said.
The system is based on dual-modal Fourier-transform spectroscopy enabled by the use of nonlinear optical effects. Inside the complementary vibrational spectrometer, a…READ MORE
