A variety of basis sets are examined including (aug-)cc-pVXZ (X = D, T, and Q), jun-cc-pVDZ, along with def2-SVP, def2-SVPD, def2-TZVP, and def2-TZVPD. Auxiliary basis sets for the RI approximation were matched to these target basis sets. Although it is well-established that MP2 overestimates dispersion interactions, the primary purpose of this work is to test the accuracy of the DLPNO approximation, not the accuracy of MP2. Moreover, a CBS extrapolation of the MP2 energy often serves as the foundation upon which a smaller-basis CCSD(T) correction is added, in the spirit of focal-point analysis.
