A local version of ORCA 4.2.1 was used to calculate the doublet-doublet excitation energies for the radical set. A total of 29 functionals were assessed, as listed in Table . All functionals assessed herein are available in the newly released ORCA 5. As explained in Ref. 20, the SCS fit for B2PLYP and ωB2PLYP led to the SOS variant. Herein, we use the shorthand notation "SOS-B2PLYP" and "SOS-ωB2PLYP" to refer to these two functionals-which are labeled SCS/SOS-B2PLYP21 and SCS/SOS-ωB2PLYP21, respectively, in Ref. 20. Note that we did not assess DFAs from rungs one to three of Jacob's Ladder as it is has been established that they are not suitable for the description of excitation energies due to large errors and the emergence of ghost states. Instead, we focus on the assessment of new or popular DFAs from rungs four and five.
