The parameter a C in Eq. 3 scales the CIS(D) contribution akin to ground-state DHDF calculations. According to Schwabe and Goerigk, 17 TD(A)-SCS/SOS-DHDF excitation energies are obtained by adding a SCS/SOS-CIS(D) ∆E TD(A)-hybrid can either be based on a global or range-separated DHDF description. An alternative SCS/SOS-DHDF definition in which the SCS/SOS-CIS(D) part is split into short-and long-range components has been recently suggested but cannot be tested herein for technical reasons. Instead, we focus on TD(A)-DHDFs as defined above.
