Abstract The dissociation equilibrium of CO, CN, C₂, CH, NH and OH is considered for the maximum and minimum phases of the light curve of δ Cep. Concentration-optical depth curves show that with both the phases the abundances decrease in the order CO, OH, CH, NH, CN and C₂. The amplitude of the abundance variation decreases in the order CO, CN, C₂, OH, NH and CH.
