Abstract
The antiferroelectric phase transition in H2C4O4 crystals is analyzed using the neutron diffraction and high resolution 13C, 17O NMR data, Hartree–Fock, Moller–Plesset and DFT calculations. Is shown that AFE phase transition is of mixed order–disorder and of displacive type represented within of the unified vibronic interaction model.
