Prior to analysing the performance of TD-DFT methods, a sufficiently reliable reference method that is still feasible for larger systems must be identified. An appropriate reference method should minimise the computational cost while maintaining reasonable comparability to a higher level of theory. Coupled-cluster WFT methods are considered the gold standard of chemical accuracy. For ground states, coupled-cluster singles-anddoubles with perturbative triples, CCSD(T), 156 at the CBS limit is the ideal that many aim to achieve in contemporary benchmarking. It constitutes a very accurate approximation to the true interaction energy of noncovalently bound complexes in their electronic ground state. One excited-state equivalent to ground-state treatments with CCSD(T) is linear-response CCSD enhanced with a different type of perturbative triples correction, such as the aforementioned CCSDR(3). It delivers excitation energies that are similar to the more costly linear-response approximate coupled cluster singles doubles triples (CC3); for examples of CCSDR(3) and CC3 being established as benchmarks and comparisons between both, see Refs 51,52, and 162-165. While the ground-state gold standard has, in recent years, become increasingly feasible for large systems of up to several hundred atoms, 166,167 the excited-state equivalent remains prohibitively expensive. For most of our systems, CCSDR(3) is therefore not achievable for computational reasons, and in the following we identify if instead CC2 or its spin-component-scaled 128 vari-ant, SCS-CC2, can be used as a low-cost alternative.
