Abstract
The electron-vibrational bands of neutron scattering by mixed valence(MV) molecular crystals containing clusters of transition metal ions in different states of oxidation as the structural units of lattice are considered. The neutron scattering band shape calculation in different phase states is performed in the semiclassical limit for crystals consisting of trielectronic clusters of transition metals of the type of d1 - dR. The shape of neutron scattering bands closely depends on the double and Heisenberg-type exchange parameters and the temperature dependence of the average dipole moment playing the role of the order parameter. The temperature dependence of the band shape brings the information about the parameters of vibronic interaction and charge ordering.
