According to our DFT-calculations (B3LYP/6-311+G*) the ''n'' and 𝜋 orbitals of the diazapyridine unit differ in the ''cis'' and ''trans'' configuration, similar to the parent azobenzene. The highest occupied orbital with coefficients located at the azopyridine unit is considerably higher in energy for the ''cis'' as compared to the ''trans'' isomer (E<sub>cis</sub>=-6.19 eV(MO=219)), (E<sub>trans</sub>=-6.53 eV(MO=216)).

Interpretation of STS-spectra

According to our DFT-calculations (B3LYP/6-311+G*) the n and 𝜋 orbitals of the diazapyridine unit differ in the cis and trans configuration, similar to the parent azobenzene. The highest occupied orbital with coefficients located at the azopyridine unit is considerably higher in energy for the cis as compared to the trans isomer (Ecis=-6.19 eV(MO=219, n type orbital)), (Etrans=-6.53 eV(MO=216)).
