Following the extensive characterization of the relevant electronic states, we have considered spectroscopic signatures of the scaffold's isomerization. The calculations show that the OCC can witness and report on the isomerization process. The azobenzene's scaffold allows the OCCs excitation energy to report on its changing environment. Functionalization of the azobenzene's frame with a second OCC results in a model system in which the first OCC can experience anisotropy of the space through which the isomerization process takes it. Correlation between the excitation energy changes and the assumed isomer gives a spectroscopic probe for observation of the isomerization chemistry.
