BL43IR of SPring-8 has been constructed for the infrared materials researches, and it covers a wide spectral range from 100 to 20,000 cm À1. The microspectroscopy station of this BL has a spatial resolution smaller than 10 lm in diameter in the mid-infrared region without apertures. This station had been mainly used within mid-infrared region, and its(More)
A new technique to investigate chemical structures of very thin surface (mesoscopic scale) layers of polar polymers is proposed. The chemical structures and conformations of ∼100 nm-thick slabs that were obtained from a polymer surface were studied by infrared spectroscopy combined with a previously developed thin sample preparation system. The dielectric(More)
The mold temperature dependence of bisphenol A polycarbonate (BPAPC) in the view of changing the "flexed state" was investigated by mid-infrared spectroscopy combined with a previously developed thin sample preparation system. The differences in the samples of different mold temperatures were clearly detected. The structural changes in the flexed state of(More)
We developed a new sampling system, the Nano Catcher, for measuring the surface chemical structure of polymers or industrial products and we evaluated the performance of the system. The system can directly pick up surface species whose depth is on the order of approximately 100 nm and can easily provide a sample for a Fourier transform infrared (FT-IR)(More)
The THz spectra of amino acids after application of spots of acetone were measured. The 0.6 THz band was commonly observed in many amino acids that formed the intra-molecular salt structure. The band can be attributed to the interaction vibration from the common structural configuration of amino acids and acetone molecules. The evidence suggests that the(More)
