Pseudospin-electron model in the case of Coulomb interaction absence is investigated. Analytic equations for specral densities within the framework of the dynamical mean field theory (DMFT) using diagrammatic series and Wick's theorem are established. The effect of the asymmetry field $h$ and tunneling-like splitting level in the local anharmonic well on the existence and number of electron subbands is investigated.
