Comparison of approximate activation Gibbs free energies (ΔGǂrot) calculated with BP86+D3 and DLPNO-CCSD(T) methods for the E to Z rotations around C9-C10, C11-C12 and C13-C14 double bonds that lead to 9-cis, 11-cis and 13-cis 1a isomers, respectively, catalyzed by complexes I or XV (see Figure 1). All values in kcal/mol.
