Q-band assignments: The magnetic circular dichroism (MCD) spectra of directly fused porphyrins have been measured (see picture), and their Q bands assigned based on the results of INDO/s calculations. On the basis of Michl's perimeter model, the calculated frontier molecular orbitals can be correlated with the observed positive MCD signs in the near-infrared region.
