The band and bound states of double electronic excitations of antiferrodielectrics are considered; from the equation for Green's function the excitation spectrum of an anti‐ferrodielectric under creation of two electronic excitations in a crystal is obtained. The absorption spectrum of a molecular antiferrodielectric, of solid α‐oxygen, is considered as an example in the frequency range of double electronic 1 Δ g + 1 Δ g , 1 Σ g ++ 1 Δ g , 1 Σ g ++ 1 Σ g +transitions.
