Outline of Final Research Achievements

We report novel MIR spectroscopy, which is the combination of an ultra-broadband MIR coherent light source and the chirped-pulse up-conversion (CPU) technique. Moreover, attenuated total reflectance spectroscopy connected with the CPU technique for observing the chemical reaction dynamics of liquid samples on real-time. We succeeded in observation of the changes of absorption spectra of liquids samples in the region from 200 to 5500 cm－1 with 1 ms time resolution by using the novel MIR spectroscopy. We believe that this unique system is useful for advanced studies of biological tissues.
