✦ Synopsis

It is shown that solitary-like excitations exist in the kinetic Ising model modified by the pseudospin-phonon interaction, at least in a particular case when the group, i.e. soliton velocity is equivalent to the phase velocity of constituent waves. The solitary waves arise due to both the tunneling mechanism and pseudospin (proton) correlations, directly and through the heavy ions. The dynamics of some prefered array of hydrogen bonds as well as of the H-bonded ferroelectric as a whole is briefly discussed.
