The molecule above was used for analysis. For the first molecule, the hydrocarbon substituents were removed.

Analysis through a semi-empirical approach

For the semi-empirical approach, Paramagnetic Method 3 was the selected theory used.

This calculation took 40.6 seconds to complete.

Analysis through an ab initio approach

For the ab initio approach the Hartree Fock (HF) theory was used
