The ground-state minima of the two isomers (cis and trans) of the azomethane molecule were optimized using the DFT method with the B3LYP functional. The frequency analysis was performed to confirm these minima are stationary. The vibrational frequencies were further used in the Wigner sampling process. The CASSCF method was used to obtain the adiabatic energies, gradients, dipoles (permanent and transition dipoles), and NAC of the azomethane molecule in the electronic structure calculations. Following the previous studies, two state average with an active space of six electrons in four orbitals [SA-2-CAS(6,4)] was used in the CASSCF calculations. In all electronic structure calculations, the 6-31G* basis set was used. The DFT and CASSCF calculations were performed using the Gaussian 16 and Molpro 2015 57 packages, respectively.
