摘要：
The incoherent inelastic neutron scattering study in a KHCO3 single crystal is reported. KHCO3 crystal contains (HCO3)(2) dimers linked by hydrogen-bonds. Neutron scattering experiments were done in order to study the hydrogen motions in the dimer. Two OH bending modes were detected, with polarizations one in the dimer plane and the other out of this plane. The obtained results were analyzed by comparing with recent infrared, Raman and powder neutron scattering data. The angular dependence of the neutron scattering spectra was found to be very useful to identify the hydrogen modes in crystalline slates.
