Many proteins contain metal porphyrin molecules. The general structure of the porphyrin molecule is This molecule is planar and so we can approximate the πelectrons as being confined inside a square. What are the energy levels and degeneracies of a particle in a square of side a ? The porphyrin molecule has 26 πelectrons. If we approximate the length of the molecule by 1000 pm, then what is the predicted lowest energy absorption of the porphyrin molecule? (The experimental value is ≈17000 cm^-1.

SOLVED: The chemical structure of porphyrin is described as a(n)a. Cyclic tetrapyrroleb. Heterocyclic pyrrolec. Linear tetrapyrroled. Oxygen-binding prosthetic group

The particle on a ring is a useful model for the motion of electrons around the porphyrin ring (2), the conjugated macrocycle that forms the structural basis of the haem (heme) group and the chlorophylls. The group may be modelled as a circular ring of radius 440 pm, with 22 electrons in the conjugated system moving along its perimeter. In the ground state of the molecule each state is occupied by two electrons. (a) Calculate the energy and angular momentum of an electron in the highest occupied
