Title: Terahertz Microspectroscopy and Infrared Reflection-Absorption Spectroscopy Apparatuses at UVSOR-II

Abstract

We have recently constructed two specialized end stations, one is the terahertz microspectroscopy (THz-MS) and the other the infrared reflection-absorption spectroscopy (SR-IRAS). Both instruments have been tested using synchrotron radiation in the infrared and terahertz regions at UVSOR-II. The THz-MS station covers the wavenumber region of 15,000 -40 cm-1 with the spatial resolution as same as the wavelength. This apparatus is a powerful tool for the electrodynamics on strongly correlated materials at low temperatures and under high pressures and also for the molecular vibration imaging of living cells. On the other hand, the SR-IRAS station covers the IR range down to 300 cm-1 with a high accuracy. The change of Al-N stretching and pyramidalization modes at 423 and 460 cm-1, respectively, due to potassium doping in Alq3 molecules on an Ag surface was observed.
