In this work, we used a range of hybrid and double-hybrid (DHDF) density functionals to calculate doublet-doublet excitation energies in small radicals. The study of open-shell systems with time-dependent DHDFs was the first detailed of this kind, and our aim was to shed light on the current state-of-the-art techniques in the field and to clarify if there is still room for future improvements. The performance of 29 functionals was evaluated by comparing the calculated excitation energies against UCC3/augcc-PVTZ reference energies from Ref. 38.
