Kinetic (non-equilibrium) abundances of the aluminium-bearing species in the post-shock gas of the SRV model after a complete pulsation cycle (phase Φ = 1.0) as a function of radial position. Dashed lines show the abundances when the AlOH photodissociation is excluded. Upper panel: initial abundances given by chemical equilibrium. Lower panel: initial abundances corresponding to a pure atomic gas composition.
