Here the ∆M s = 0 label indicates that the density matrix γ ∆Ms=0 is computed for the spinconserving excitations. Importantly, this applies not only to the EOM-EE ansatz, but also to the EOM-SF, EOM-IP, and EOM-EA variants for the transitions between the states with the same spin projections. Non-zero spin blocks are denoted as γ ∆Ms=0 αα and γ ∆Ms=0
