Tóm tắt

A spectroscopic system for the far-infrared region is described which was constructed at beamline BL6A1 of the UVSOR facility at the Institute for Molecular Science (Okazaki) and has been used since 1986. Intensity measurements at UVSOR proved that synchrotron radiation is a very bright source compared with a blackbody source throughout the entire far-infrared region. To demonstrate the advantages of synchrotron radiation in the far-infrared region, results on a reflection measurement of a small specimen and an absorption measurement under high pressure using a diamond anvil cell are shown. From the measurement of the shift of the TO phonon energy of KI with pressure, the mode Gruneisen parameter at room temperature was determined to be 1.70.
