The particle on a ring is a useful model for the motion of electrons around the porphine ring, the conjugated macrocycle that forms the structural basis of the haem group and the chlorophylls; see the structure of the porphine molecule below. -NH HN- We may treat the structure as a circular ring of radius 440 pm, with 22 electrons in the conjugated system moving along the perimeter of the ring. Assuming that, in the ground electronic configuration of the molecule, each state is occupied by two electrons, calculate:
