Hydrogen bonds in molecular crystals are one of the research areas extensively investigated by the single-crystal neutron diffraction technique. SENJU, a time-of-flight Laue-type single-crystal neutron diffractometer at J-PARC, is one of the world's limited single-crystal neutron diffractometer capable of measuring a sub-millimeter size molecular crystal. In this presentation, the authors will show what kind of structural research of hydrogen bonds in functional molecular crystals, e.g., proton transfers in temperature-induced spin-transfer metal complexes and a salt-cocrystal continuum formation in a photo-functional organic crystal, conducted at SENJU.
