However, often correlation-consistent basis sets are applied in coupled-cluster treatments. In addition, calculations with larger basis sets are frequently performed on top of calculations with a triple-ζ basis set in order to extrapolate towards the complete basis set limit. Therefore, the accuracy of the proposed multi-level DLPNO-CCSD(T 0 ) method is analyzed below in dependence on the basis set. We employ the def2-TZVP, def2-QZVP, cc-pVTZ, and cc-pVQZ basis sets for this purpose. For these basis sets and the respective extrapolated values, the MADs and SDs of the reaction energies and barrier heights calculated with pair-selected multi-level DLPNO-CCSD(T 0 )
