(detailed results are presented in the supporting information). Generally speaking, DLPNO-CCSD/DLPNO-CCSD(T) is the most accurate when modeling dimers bound by mixed influences, versus modeling hydrogen-bonded or dispersion dominated dimers. It is also shown that adding diffuse functions (as in the case of the jun-cc-pVDZ basis set) helps reduce the errors associated with modeling dispersion interactions relative to DF-CCSD(T).
