One well-known flaw of TD(A)-DFT is its inability to describe transitions with high doubleexcitation character due to the adiabatic approximation. TD(A)-DHDFs are no exception to this and in fact their high amount of Fock exchange can further increase deviations. Upon closer inspection of the WFT data in the original paper that published the herein assessed radical set and after additionally conducted UCCSD calculations of systems with deviations of more than 0.5 eV for DHDFs that are known to usually perform well, we identified excitations with high doubleexcitation or multi-reference character. The relevant systems and states that caught our attention after such an analysis are CNO (state 2 Σ + ), CO + (state 2 Π) and NCO (states 2 Σ + and 2 Π).
