Current status of single crystal SR x-ray structure analysis at high pressure at SPring-8

In this article, we review recent activities at BL02B1 at SPring-8 in the field of single-crystal and high-pressure X-ray diffraction experiments. A comparison of experiments performed two decades ago with the new frontier experiments is also shown. Special attention is paid to the importance of the quantitative arguments. The characteristics of the single-crystal and high-pressure experiments are also compared with the powder-sample and high-pressure experiments.
