摘要：

Detailed structure analysis of MeHPLN (C14O2H14, 5-methyl-9hydroxy-phenalenone) by X-ray and neutron scattering experiments were performed. By comparing the distribution of electrons and nuclei of hydrogen atoms participating in the hydrogen bond, we have found peculiar difference of the center of mass of electrons and nuclei. Such displacement of electrons introduces a local dipole moment, which may play an important role in the phase transition of this hydrogen-bonded material.
