Synchrotron radiation has been recognized to be a very powerful light source in the X-ray and soft X-ray regions. However, the utilization has not been enough reallized in the infrared region. The purpose of the present research is to make clear the advantage of synchrotron radiation in the infrared region overconventioanal light sources by demonstrating experiments which have been difficult to carry out by con-ventioanal light sources can be easily done by synchrotron radiation. We performed high pressure experi-ment above 10 GPa using a diamond anvil cell in the far-infrared region and could find drastic changes in the phonon spectra of various materials due to the structural phase transition under pressure. In order to prove that synchrotron radiation is a useful pulsed light source in the infrared region, we did the observa-tion of the pulsed infrared light beam from UVSOR,the fascilities of the electron storage ring of Institute for Molecular Science at Okazaki, by using infrared detector MCT with a fast response and confirmed UVSOR to be very excellent light source for a time-resolved spectroscopy in nanosecond time domain.

同步辐射被认为是X射线和软X射线领域中非常强大的光源。然而，在红外波段的应用还没有得到充分的实现。本研究的目的是通过证明用同步辐射可以很容易地完成用常规光源难以完成的实验，来阐明同步辐射在红外区优于常规光源的优越性。我们用金刚石压砧在远红外区进行了10GPa以上的高压实验，发现在高压下，由于结构相变，各种材料的声子谱发生了剧烈的变化。为了证明同步辐射在红外区是一种有用的脉冲光源，我们用具有快速响应的红外探测器MCT对冈崎分子科学研究所电子储存环的电子束UVSOR的脉冲红外光束进行了观测，证实了UVSOR是纳秒时间分辨光谱的一种非常好的光源。
