The shapes of spectral features that can take place in the Rayleigh-Jeans region of the microwave background spectrum are calculated. These distortions are produced at z=10-30 by H_2_D^+^ molecules that are absorbing the non-equilibrium photons of the primordial distortions of CMBR spectrum in the Wien region (connected with the energy release in the early Universe) and that are emitting photons in wavelength region λ=1-100mm. It is shown that with reasonable values of the initial distortions spectral features emerge that can have sufficiently large amplitudes to be detectable.
