Porphyrin is a large flat conjugated molecule explains which can be thought of as having a square box shape. Apply the 2D particle in a square box model to the 22π elctrons of porphyrin. The length of each side of the box (L) is 615pm. The 2D model can encompass degenerate energy levels. For various combinations of the n(x) and n(y), compute the energies of the eleven lowest energy levels which will accommodate the 22π electrons.
