Abstract: For photo-excited crystallography at low temperature using micro-crystals, a new low-temperature vacuum X-ray camera (LTV camera) has been developed and installed at SPring-8 BL02B1. By eliminating X-ray scattering from air and vacuum windows, we successfully obtained high quality data below 80K. we have also developed a special data collection system, multiple exposure IP method, by which both diffraction patterns from the crystal on light irradiated and unirradiated conditions can be recorded on the same image of an IP detector.
Molecular distortion of a photo-excited diplatinum(II) complex in a single crystal has been directly observed by accurate synchrotron radiation studies using the LTV camera and multiple exposure IP method. Photo-excited crystallographic analysis has revealed that a small portion of [Pt₂(pop)₄]^4- (pop=H₂O₅P₂^2-) complex shows the Pt-Pt bond shrinkage of 0.23 Å under blue laser irradiation.
