Most synchrotron facilities offer a port dedicated to infrared (IR) spectroscopy and infrared-microspectroscopy. The main advantage of synchrotron-based infrared spectroscopy is the brightness of synchrotron radiation source. The synchrotron radiation source provides brightness 2-3 orders of magnitude higher than a thermal (Black body radiation) infrared source. Thus, synchrotron based infrared spectroscopy has allowed high spatial resolution (infrared micro-spectroscopy) and high spectral resolution. In 2016, the first Infrared beamline (IRS @ 12D port) was constructed at the Pohang Accelerator Laboratory (PAL) in Korea and started the general users operation in 2017. Synchrotron-based infrared spectroscopy and its applications will be presented. In addition, the current status of infrared beamline of PAL will be discussed. |
