This molecule is planar, so we can approximate electrons as being confined inside a square. What are energy states/levels and corresponding degeneracies of a particle in a square of side a? Porphyrin molecules have 18 T electrons. Consider each state as a molecular orbital. Fill those electrons in the corresponding molecular orbitals. If the length of the molecule is 850 pm, what is the lowest energy absorption of the porphyrin molecules? (The experimental value 17000 cm-¹).
