With monomer geometries, energies, and SOC stabilization corrections evaluated in the previous sections, we here wish to extend the analysis to dimers consisting of atmospherically relevant precursors described in Section 2. While a larger ensemble of each type of dimer was created, we only carried out this benchmark for the 5 lowest free energy structures of each dimer, calculated at the ωB97X-D3BJ/aug-cc-pVTZ-PP level of theory. In this section we use the following definition of the error and relative values:
