  The behavior of the subsystem of hydrogen atoms of the KIO_3*HIO_3 crystal,
whose IR absorption spectra exhibit equidistant submaximums in the vicinity of
the maximums in the frequency range of stretching and bending vibrations of OH
bonds, is studied in the present work. It is shown that hydrogen atoms
co-operate in peculiar clusters in which, however, the hydrogen atoms do not
move from their equilibrium positions, but become to vibrate synchronously. The
interaction between the hydrogen atoms is associated with the overlapping of
their matter waves, or more exactly, the waves' substructure, a very light
quasi-particles called inertons, which play the basic role in submicroscopic
quantum mechanics that has recently been constructed by the author. The number
of atoms, which compose the cluster, is calculated.
