Jc 7F.1 Use the particle-on-a-ring Self-test model to calculate the energy required for the excitation of a T 'minimum electron in C2H2. Assume that the radius of the coronene ring is three times the carbon-carbon bond length in benzene and that the electrons are confined to the periphery of the molecule. F.1l iS e.
