Table . Root-mean-square deviations (RMSDs) in excitation energies [eV] and spin-orbit coupling matrix elements (SOMEs) [cm -1 ] of TDA@PBE0 results with respect to reference TDA@PBE0 and DFT/MRCI results taken from Ref. . For comparison, RMSDs comparing the reference TDA@PBE0 computations with the reference DFT/MRCI results are listed in the last column.
