Thermochemical parameters, including zero-point energy (ZPE), atom-energy corrections (AECs), and bond-additivity corrections (BACs), were computed in the rigid rotor harmonic oscillator (RRHO) approximation limit using the Arkane 43 software package, following the procedures described in Part 1. For ZPE calculations, the frequency scaling factors recommended by Keshawarwani et al. were applied. These corrections were applied to the electronic energies obtained from the QM calculations to yield the final corrected enthalpies of formation (∆H • f ) at 298 K that can be directly compared to the known reference values.
