AbstractThe multi-photon photodissociation (MPD) action spectrum of the coronene cation $$({{\rm{C}}_{24}}{\rm{H}}_{12}^ + )$$ has been measured as a function of storage time up to 60 s in the cryogenic electrostatic storage ring DESIREE. These measurements reveal not only the intrinsic absorption profile of isolated coronene cations, but also the rate at which hot-band absorptions are quenched by radiative cooling. The cooling rate is interpreted using a Simple Harmonic Cascade model of infrared vibrational emission.
